I'm running Mathematica 3.0 on an SGI 02 and get a core dump when I
execute the following code (or any variation thereof).
Clear[mat1,mat2];
mat1 = Array[a,{5,5}];
mat2 = Array[b,{3,3}];
mat1[[{1,3,5},{1,3,5}]] = mat2;
The following code works fine:
Clear[mat1,mat2];
mat1 = Array[a,{5,5}];
mat2 = Array[b,{3,3}];
mat1[[{1,2,3},{1,2,3}]] = mat2;
Could someone explain what is happening here? Also, how should I
implement the first example without crashing the system?
