visualization with matlab
dear all,
I have obtained some results of my numerical simulation and now I need to visualize them. As I don`t have any commercial tools at my disposal other than Matlab, I`m trying to visualize the results using that software. I want to make a 2D contour plot of a field data, and I have written a Mfile like the following:  load('zet') / 'zet is the field data' n=2349; rangex=[0 0 n 0]; rangey=[0 1 n 1]; rangez=[0 2 n 2]; x=dlmread('zet',' ',rangex); /x is xcoordinate array y=dlmread('zet',' ',rangey); /y is ycoordinate array z=dlmread('zet',' ',rangez); /z is the data array contour(x,y,z);  The file was successfully compiled, and the graph window appeared, but there was nothing in the window except axis x and y. Could anyone help me solve this problem please? Thanks so much for your kind help regards, lola 
Re: visualization with matlab
MATLAB include facilities using MEX file to call C & FORTRAN routines from within MATLAB. Also you can use MATLAB engine to call MATLAB functions (including those of Data visualization) through C or FORTRAN program. The MATLAB document which discuss MATLAB API and external programming provided neccessary details along with examples.
