Hello!
There is a file, where 50x50 values are written, all in all 2500 values. They are written like this:
1
2
3
4
5
...
...
2499
2500
Therefore one value is in every string How to read data from this txt-file in Array A of dimension 25x25, so the first 25 values was the first row of the array, the second 25 second, and so on until the end?
Tried this:
fileI = fopen('file.txt','r');
formatSpec = '%f';
sizeA = [50 50];
Vx = fscanf(fileI,formatSpec,sizeA);
fclose(fileI);
Vx=Vx';
But it does not work, the whole array fills with zero.
Thanks in advance!

fileI = fopen('file.txt','r');
Vx = fscanf(fileI,'%f');
fclose(fileI);
out = reshape(Vx,50,[]);
