fid = fopen('File:', 'rt');
datacell = textscan(fid, '%s%f%f', 'Delimiter', ',');
fclose(fid);

datastruct = struct('Field1', datacell{1}, 'Field2', datacell{2}, 
'Field3', datacell{3});


The result will be a structure array, one array element per row, with 
the field named "Field1" containing the initial string, the field named 
"Field2" containing the first number, and the field named "Field3" 
containing the second number.

Putting it in to a matrix requires more information from you about the 
shape you want the matrix to be, as it would be necessary to use a cell 
matrix rather than an ordinary numeric matrix.
