Fail

%% M = magic(5); v = 1:3; d = 2; M2 = M; M2([11,17,23]) = v; assert(isequal(setDiagonal(M,v,d),M2));

Error: Matrix dimensions must agree.

3

Fail

%% M = rand(6); v = [.2 -.2]; d = -4; M2 = M; M2([5,12]) = v; assert(isequal(setDiagonal(M,v,d),M2));

Error: Matrix dimensions must agree.

Fail

%% M = zeros(99); v = ones(1,99); d = 0; M2 = eye(99); assert(isequal(setDiagonal(M,v),M2)); assert(isequal(setDiagonal(M,v,d),M2));

Error: Matrix dimensions must agree.

5

Fail

%% M = zeros(3); v = -1:1; d = 0; M2 = diag(v); assert(isequal(setDiagonal(M,v),M2)); assert(isequal(setDiagonal(M,v,d),M2));

Error: Matrix dimensions must agree.
