Error mxCreateDoubleMatrix_730 in libmx.dll
Hello, When I compile a cpp file in VS 2010 calling Matlab functon, I received this error message saying: The procedure entry pint mxCreateDoubleMatrix_730 could not be located in the dynamic link library libmx.dll. I have no idea how to solve it. Please leave me a message if anybody know the answer. Many t... 10 May 2010 08:45

3D plots - what did I do?
I've been looking at making volumetric data from vectors of X,Y,Z and R. X and Y are UTM co-ordinates, and Z describes 5 different elevations at each XY couple. For each XYZ point there is a data value R. I start by arranging x and y so that there is a seperate data point for each z, i.e the same x and y co-ordinate... 10 May 2010 08:45

Matlab compiler for embedded software
Hello, I am trying to compile some matlab code in C files that I will then use to cross-compile for an ARM processor on an embedded system. Is this possible? So far I was able to use mcc to generate the C source files and a standalone app that I was able to use. But I am unable to cross-compile the C source file ... 10 May 2010 09:51

Comparing each element for two matrices
Hi all, I have two matrices, each with size of 5x11. I would like to compare each element in each matrix with a value. I use if for this purpose: if (Xh_channel <= 0.24 && Xt_channel >= 0.15) %pass = 1; for i = 1:size(x_var,1) Nu_mean=interp1(linspace(1,0.166667,size(y_var_nu_ch... 10 May 2010 10:57

Comparing frames of video
HI I have a project to complete! I could read the files from a video clip using mmread. I tried with the MMREADER, but every time code returned error messages. Now with MMREAD or with AVIINFO, I can see the frame numbers of the video. AVIINFO reads AVI files only. Anyway, both of these funtions returns ... 12 May 2010 10:14

Fit equation with 3 independants
I've got an equation with three independants f(x, y, z)= 1+A*B^x *C^y*sqrt(z). I already fitted the equation to a surface with sftool, assuming y as a constant value but that won't give me correct values for A,B,C i think. So what i need is a tool like sftool, but with the option to have 3 independants. Not important... 10 May 2010 09:51

percision in matlab command imdivide
I am making a code in which i have to divide two images using imdivide command. I am expecting to get assigned values to the image pixels between 0- 1 but the final outcome is values 0 and 1 (only integers). Is it possible to get better precision ( that is decimal points) rather than just integers . The Input is double... 10 May 2010 07:39

Plotting a 3-D line plot with user defined axis.
I have the x, y and z coordinates of a particle at different times in a matrix and I plotted them on a graph plot3(point(:,1),point(:,2),point(:,3)) However, I need the x and z axis to switch positions i.e. the x axis should be the vertical one while the z axis the right hand axis. Is there a way to write a code ... 10 May 2010 12:04
