This is in continuation to a question Image Shuffling in one of my threads %# scramble autumn.tif with itself img1 = imread('autumn.tif'); %# scramble [dummy,scrambleIdx] = sort(img1(:)); img2 = img1; img2(:) = img1(scrambleIdx); %# note the (:). If you don't use it, img2 becomes a vector %# unscramble [dummy2,unscrambleIdx] = ...
I wonder why these two code doesn't produce the same plot? code 1: x=[2,5,7]; y=[10,4,3]; plot(x,y); code 2: x=[2,5,7]; y=[10,4,3]; for i=1:length(x) xx=x(i); yy=y(i); plot(xx,yy); end EDITED: How I can make the output of Code 2 similar to output in Code 1 ...

Hello , I am a new user of matlab . i can use auto word completion at matlab command promt by tab . but i can not do that while using the editor for m file . Is there any option using the editor , Than please inform me . thank you . ...
To generate an ouput file (.rwo format) containing the desired result, we have to run the executable of the report program which uses a parameter file (.rwd format). The output file is ReportBHP1.rwo, this file will contain the variable exported. Now to implement this in Matlab, below is a small script giving a gist of what I am trying ...
I have 6 vectors which I want to plot. How I can make each plot with different color (random)? With the code below, the plot limited to one color for all six vectors. plot(x,y,'-rs','LineWidth',1,... 'MarkerEdgeColor','k',... 'MarkerFaceColor','g',... 'MarkerSize',5); ...
I like to create a "report generation" script in Matlab. Suppose we have a Matlab array, data and we want to export the following to a .tex file: "The information in the first element of data is X." This would be followed by a plot of X. I have already tried help latex in Matlab and aware of the various packages on Matlab file exchang...
I have two cell arrays of strings, and I want to check if they contain the same strings (they do not have to be in the same order, nor do we know if they are of the same lengths). For example: a = {'2' '4' '1' '3'}; b = {'1' '2' '4' '3'}; or a = {'2' '4' '1' '3' '5'}; b = {'1' '2' '4' '3'}; First I thought of strcmp but it would r...
This is a class assignment. I had written some codes which I hope someone can help me. This is the code that I have % --- This is optional to verify whether my parametrization is consistent with the % --- original equation % syms x y z p t % ellipsoid=[2*sin(p)*cos(t),4*sin(t)*sin(p),sqrt(2)*cos(p)] % simplify(subs((x^2/4)+(y^2/16)+(...
My customer is sending TDM/TDX files captured in National Instruments Diadem, which I haven't got. I'm looking for a way to convert the files into .CSV, XLS or .MAT files for analysis in Matlab (without using Diadem or Diadem DLLs!) The format consists of a well structured XML file (.TDM) and a binary (.TDX), with the .TDM defining how ...
I have a line in the code I'm working on like this: feval('func_name', myArg); And it works, but I want to know where func_name is. I can't step into feval to see where it is finding func_name. Instead of (or in addition to) just doing func_name, how can I get MATLAB to tell me where it found it? ...
I want to plot a 3d graph in matlab By graph I mean in the sense of nodes and edges. I have an adjacency matrix as well as a coordinate matrix for every node. Eventually I would hope to colour these nodes and edges The gplot function is only 2d. The scatter3 function does not allow for edges. Any ideas? ...
I have the following structure in matlab superClass < handle subClassA < superClass subClassB < superClass say I have a vector A of subClassA and a vector B of subClassB. I would like to combine them like this: superVector = [A B]; but Matlab doesn't like this. What's the proper way to cast the subclass back to the superclass...
In MATLAB, is it possible to create a single graph of two related data sources with the first source plotted along the bottom of the x-axis and the 2nd source plotted down from the top of the x-axis? I can't find anywhere in the MATLAB documentation where this is done. The final graph I need is in a form like this: ...
Or is there a built-in function that can do exactly this job? ...
Hi! Just imagine you plot several dots, circles, lines in a figure. Afterwards another m file should use this plot as an input to do e.g. thresholding. I'm aware of the print command but I don't want the plot to be stored as file. I would prefer to store it in a matrix (x_dim,y_dim,3). Any ideas? ...
I've inherited some code where the author had an aversion to semicolons. Is it possible to fix all the mlint messages in one go (at least all the ones with an automatic fix), rather than having to click each one and press ALT+ENTER? ...
In my Simulink model are some embedded MATLAB functions. Is there a way to get the content (the text you see in the editor) of this blocks? My first guess was to use find_system to get the embedded MATLAB functions and then get_param to get the content. But I dont find the needed parameter name. The documentation didnt show up any param...
I'm trying to connect to MySQL using MATLAB R2009b 64 bit and the mysql.cpp file found on the FEX and here. I followed all the steps to compile listed in the second link. After entering the following: mex -I"C:\mysql\include" -DWIN32 mysql.cpp "C:\mysql\lib\opt\libmySQL.lib" the mysql.mexw64 file is created in my working directory. Ho...
Possible Duplicate: Growable data structure in MATLAB So in my current MATLAB script, I have a very large indeterminate-sized growing array. There is currently nothing I can do about it, because if I actually preallocate, it would take many many many times more memory than it should need (maximum possible amount of values is 6...
