How do I implement such an invertible mapping(one-to-one) for curves using MATLAB?
So that several curves X,Y can be mapped to another curve R,which is invertible so that I can still get X,Y from R. Anyone has ideas for this or perhaps some term I can google it myself? UPDATE I think some clarifications are deserved here. map(X,Y) => R; invertible_map(R) => (X,Y) ...
Write a MAT file without using matlab headers and libraries.
Hello all, I have some data that I would like to save to a MAT file (version 4 or 5, or any version, for that matter). The catch: I wanted to do this without using matlab libraries, since this code will not necessary run in a machine with matlab. My program uses Java and C++, so any existing library in those languages that achieves this...

Problem with input filter using doxygen 1.6.3 on windows XP
I am trying to use doxygen to generate documentation for some matlab classes I have written. I am using the doxygen-matlab package, which includes a perl script to kludge matlab .m files into c++ style commented files, so that doxygen can read them. In my doxyfile, I have set (according to the instructions) FILTER_PATTERNS = *m=...
image processing toolbox in matlab
I've got a specific question and a related more general one... Why does imextendedmax() not give for example 9 in A(3,3) as a max? Generally... what is the best way for finding multiple maxes/peaks? The nice thing about imextended max is it allows a threshold where presumably everything under that threshold is not counted whereas imregio...
MATLAB intersection of 2 surfaces
Hi everyone, I consider myself a beginner in MATLAB so bear with me if the answer to my question is an obvious one. Phi=0:pi/100:2*pi; Theta=0:pi/100:2*pi; [PHI,THETA]=meshgrid(Phi,Theta); R=(1 + cos(PHI).*cos(PHI)).*(1 + cos(THETA).*cos(THETA)); [X,Y,Z]=sph2cart(THETA,PHI,R); surf(X,Y,Z); %display hold on; x1=-4:.1:4; [X1,Y1] = mes...

Finding many local max in an image (using MatLab)
How do you go about figuring our multiple max in a 2D image where the max aren't necessarily all the same height? I have found that the imregionalmax(), imextendedmax(), and findpeaks() functions aren't necessarily that helpful because they give many local max that are really just maxes within the background noise. I tried bw=array>imdi...

MEX-File to Output Pulse in a Loop to a DAQ-Board
Hi there, i figured I must use a MEX-File to output Digital pulses in a loop (40 kHz) from Matlab to my DAQ-Board, I have some APIs from the DAQ-Board vendor, but I really dont know if they are useful. It´s a big documentation on the Mathworks website about MEX-File and APIs, that just make me confused. So I´m asking here if someone ca...
