powerM¶
Purpose¶
Returns the power n of a matrix A, as the matrix product of n copies of A.
Format¶
-
B =
powerM(A, n)¶ - Parameters:
A (NxN square matrix) – Data.
n (Scalar) – The power or exponent.
- Returns:
B (NxN square matrix) – The power of a matrix A.
Examples¶
A = { 1 2,
3 4 };
// Compute power matrix
B = powerM(A, 3);
print "A = " A;
print ;
print "B = " B;
After the code above:
A=
1.0000000 2.0000000
3.0000000 4.0000000
B=
37.000000 54.000000
81.000000 118.00000
Remarks¶
If \(n = 0\), then the function will return an identity matrix.
