I have a logical matrix MASK and a vector VEC with real numbers (uint8 mostly). nnz(MASK) equals length(VEC).
I create a new matrix NEW where the logical 1's in MASK are replaced by the values in VEC--in sequential order:
NEW = MASK; NEW(NEW>0) = VEC;
Can I do this with 1 statement? Because in practice I want to replace NEW with VEC since I dont need VEC anymore after the operation, and don't want to pile up variables. MASK should remain untouched.
I think you can just do:
VEC(~MASK) = 0;
I think this will do the same thing - set VEC to zero where MASK is false, and VEC stays VEC where MASK is true.
By the way, you can use clear('variableName') to get rid of variables you don't need anymore.
