[Octave-bug-tracker] [bug #60784] Inconsistent behavior for boolean matrix types with matrix functions

[anonymous]

Follow-up Comment #11, bug #60784 (project octave):

>From curiosity, I did a cross product of multiple types with multiple
functions using the code at the bottom of this comment. Here are the results:


Type logical:
    Silent: add, subtract, matrix multiply, matrix ^ scalar, scalar ^ matrix,
det, lu, svd
    Warning: inv (singular to machine precision)
    Error: eig

Types int8, int16, int32, int64, uint8, uint16, uint32, uint64:
    Silent: add, subtract, inv, det, lu, svd
    Warning:
    Error: matrix multiply, matrix ^ scalar, scalar ^ matrix, eig

Types single, double:
    All functions work, no errors or warnings.


Code to test:

origA = rand(50); # type double
origB = rand(50); # type double

types = ["logical"; "int8"; "int16"; "int32"; "int64"; "uint8"; "uint16";
"uint32"; "uint64"; "single"; "double"];

funcs = ["A+B"; "A-B"; "A*B"; "A^1.6"; "(-1.6)^A"; "inv(A)"; "det(A)";
"lu(A)"; "eig(A)"; "svd(A)"];

for i = 1:size(types,1)
  for j = 1:size(funcs,1)
    str = sprintf("A = %s(origA); B = %s(origB); C = %s;",...
                  types(i,:), types(i,:), funcs(j,:));
    disp(str)
    try
      eval(str)
    catch
      disp("error for the last operation")
    end
    disp(' ')
  end
end
