So, an integer variable is a scalar value. This means that you can have any integer inside of it that you want. Scalar generally means one-dimensional, so it can be any number on that dimension, like the number line.
The value of the determinant of a matrix doesn't change if we transpose this matrix (change rows to columns). a is a scalar, A is n n matrix.If we multiply a scalar to a matrix A, then the value of the determinant will change by a factor ! If an entire row or an entire column of A contains only zero's, then. This makes sense, since we are free to choose by which row or column we will expand the determinant.f we multiply a scalar to a matrix A, then the value of the determinant will change by a factor !
