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));
