Term-by-term multiplication

Term-by-term multiplication of two matrices of the same dimensions is possible through the use of function HADAMARD. The result is, of course, another matrix of the same dimensions. This function is available through Function catalog (‚N), or through the MATRICES/OPERATIONS sub- menu („Ø). Applications of function HADAMARD are presented next:

Raising a matrix to a real power

You can raise a matrix to any power as long as the power is either an integer or a real number with no fractional part. The following example shows the result of raising matrix B22, created earlier, to the power of 5:

You can also raise a matrix to a power without first storing it as a variable:

In algebraic mode, the keystrokes are: [enter or select the matrix] Q [enter the power] `.

In RPN mode, the keystrokes are: [enter or select the matrix] †[enter the power] Q`.
