Hey guys, I am currently working on the project and have a difficulty to open .txt file in Matlab. This .txt file contains rainfall radar data in matrix (numbers) form, [m,n] = [360,90]. Below is the data I am having troble with.** ....................................................................................... Projection Metad...
I am getting stock prices from yahoo, and want to have each stock have its own time series data structure, but also don't want to have hundreds of variables, so naturally I would want to have an array, but when I do something like array = [stock1 stock2]; it actually merges the series together. How can I make a real array? Thanks, CP ...
hi i was trying to implement the amdemod given in matlab without using this function, i am not getting the answer close to the amswer given by the function. can u please let me know , wwhere is the problem. The code i tried are as follows: Fs = 8000; % Sampling rate is 8000 samples per second. Fc = 300; % Carrier frequency in Hz t = [0:...
Does MATLAB have a function that will "snap an image" or move an image to some predefined location if within a certain area? ...
we have a situation that a stream (data from sensor or click stream data at server) is coming with sliding window algorithm we have to store the last (say) 500 samples of data in memory. These samples are then used to create histograms, aggregations & capture information about anomalies in the input data stream. please tell me how to ma...
I am working with the finacial tooldbox that has a type called FINTS, If I copy some code out of its toolbox directory to customize it, when I try do do something like fts.data, I get The specified field, 'data', does not exist in the object. But the same thing works fine in the matlab library directory. They are both in my path, so wh...
Im currently an E.E. under grad. and i was curious about matlab, I am now on break and i want to take my matlab a step beyond what i know (which is beginner to intermediate). For an example, i heard about a student doing a project that involved matlab controlling sensors to detect sunlight (solar panel related) and I am not sure how he d...
Has anyone here used the Matlab Data Acquisition Toolbox before? I've been spending a ton of time reading up on National Instruments products and their capabilities when used with Labview. However, Labview and NI hardware is pretty much the only thing I've looked at and I'm curious as to what is out there that competes with labview i...
I am just wondering, if I need a toolbox which not available in my MATLAB, how do I do that? For example: if I need image processing toolbox, how do I get it? ...
I have a training set that has input and outupts in this way: Input: 0.832 64.643 0.818 78.843 1.776 45.049 0.597 88.302 1.412 63.458 1.468 49.535 1.985 33.387 2.073 30.279 1.431 55.231 1.116 68.521 1.617 44.362 2.159 66.512 Output: 0 0 1 0 0 1 0 1 0 0 0 1 0 0 1 1 0 0 0 0 1 1 0 0 1 0 0 0 0 1 0 0 1 0 1 0 1 0 0 1 0 0 0 1 0 0 1 0 I need...
I am using meshm to plot densities. How do I calculate the center point for each of the bins? I want to associate the data in m with the centerpoints I have looked at the source code of meshm and believe the solution will be a modified version of meshm that returns the latitude and longitudes of each bin's center point. meshm calls th...
Is there a way to find the mean square error in matlab between 2 images A,B(say) in true color of dimension 256*256*3 ? The mathematical formula for a matrix say M1 and M2 is as under mean sq err=1/n*n { summation (square[M1(i,j)-M2(i,j)])} where i stands for row and j stands for column ...
Hi. There is this assignment in which the first part involves dividing 3 images(RGB) A,B,C equally into A1,A2 ;B1,B2; C1,C2 Then we have to use (a) bitxor and (b)circular shift operation.The rule for bitxor is A1 bitxor B1 and A2 bitxor C2 and similarly for circular shift. Then merge the two results to obtain a mixed image. The last par...
I have a set of inequalities ( the mathematical question is expressed at math.stackexchange), and I am looking at the appropriate matlab toolbox that can do it. Is there a toolbox in Matlab that finds the range of x, given that y(x) is subjected to an inequality? But since I'm not exactly sure what is the name of this problem, therefor...
Hi. Is there an inbuilt / m file in Matlab to obtain the highly fluctuatiing and multiple peaks of the plot of an alpine function? I want to obtain a similar figure in 3D which is and The formula (probably) is z=sin(x1)sin(x2)\sqrt{x1x2} ...
Is there any way that I can simulate sensor networks in Matlab? Currently, I am coding it all the way, i.e. assigning all the properties to a sensor node in a pretty crude way using structures. A toolbox, if any would do the model some justice. Otherwise, the current simulation does not feel right. ...
