How do i extract these arrays from a .m file?

I need to get the matrices but I'm unsure how to proceed. The file in question is attached as a picture.

Thanks!

You didn't specify the number of matrices. If it is small, the easiest way is to do it manually like this,

A = [1 0 0; 
    2 0.5 0; 
    3 1 0; 
    .....;
    .....];

Similar for other matrices.

there are three matrices. And no it is not possible to hard code them as they are big for complicated cases. Basically I want the first chunk to be called a matrix A, second a Matrix B and the last a matrix C.

1 0 0 
2 0.5 0 
3 1 0 
4 0 0.5 
5 0.5 0.5 
6 1 0.5 
7 0 1 
8 0.5 1 
9 1 1 

1 1 2 5 4 
2 2 3 6 5 
3 4 5 8 7 
4 5 6 9 8 

1 1 0 
2 1 0.25 
3 1 1 
4 1 0.25 
5 0 0 
6 1 1.25 
7 1 1 
8 1 1.25 
9 1 2

If your file is formatted as above (i.e. matrices are separated by an empty line, try following code

fID = fopen('temp_.m', 'r');
fileData = fread(fID);
fclose(fID);
fileStr = char(fileData');

%%searching for empty line (i.e. 2 new lines)

partitionIndex = strfind(fileStr, [newline newline]);

A = str2num(fileStr(1:partitionIndex(1)-1));
B = str2num(fileStr(partitionIndex(1)+2:partitionIndex(2)-1));
C = str2num(fileStr(partitionIndex(2)+2:end));
