I just run the following simple code to write a binary file and then read it in MATLAB.
It produces: Error using fread! Invalid Size!!
Any idea?!
% write a binary file
clear
clc
m=uint16(randi([0 5000],100,150, 50));
f=fopen('xtest','w');
fwrite(f,m,'uint16','ieee-le');
fclose(f);
% read the same binary file!
clear
clc
x0=fopen('xtest');
pj=fread(x0,[100, 150, 50],'uint16','ieee-le');%
fclose(x0);

Amir - according to fread dimensions of output vector, this vector/array can only be a two-element row vector wheras you are trying to read a three dimensional array. You probably need to read in the data as
pj=fread(x0,[100, 150*50],'uint16','ieee-le');%
pj = reshape(pj, [100 150 50]);
I tried this for a smaller three dimensional array and it seemed to work fine.
