MATLAB: Converted vtk files are not seen

Question

I was trying to convert my 3d mat files to .vtk format using the code showed inside the below link

http://www.mathworks.com/matlabcentral/fileexchange/23416-writetovtk

For example,i was first trying to convert one mat file to .vtk file. So before the code begins this is what i typed:

filename='P3290321.mat';
matrix=size('P3290321.mat');

Output: no errors , but nothing is written either.(i am certain this code works well when looking at the comments, but i don't know what mistake i am doing here)

I wonder what happened to my converted .vtk files? Can anyone kindly guide me to overcome this issue.

Answer 1

size('P3290321.mat') means to take size() of the string 'P3290321.mat' which is a 1 x 12 char array.

If you want to use data inside of P3290321.mat then you need to load() the file and access the appropriate loaded variable.
