HP 15c Scientific ⎡4 +, ⎣1 +, Z = ⎢

Section 12: Calculating with Matrices 163

Example: Store the complex matrix
⎡4 + 3i	7 − 2i⎤
Z = ⎢	⎥
⎣1 + 5i	3 + 8i ⎦

in the form ZC, since it is written in a form that shows ZC. Then transform ZC into the form ZP.

You can do this by storing the elements of ZC in matrix A and then using the pfunction, where

	⎡4
	A = Zc = ⎢
