2-8-20 Matrix Calculations u Raising a Matrix to a Power Example To raise the following matrix to the third power : 12 Matrix A = 34 K2(MAT)1(Mat)av(A) Mdw [OPTN]-[MAT]-[ ] u Determining the Absolute Value, Integer Part, Fraction Part, and Maximum Integer of a Matrix [OPTN]-[NUM]-[Abs]/[Frac]/[Int]/[Intg] Example To determine the absolute value of the following matrix : 1 -2 Matrix A = -3 4 K6(g)4(NUM)1(Abs) K2(MAT)1(Mat)av(A)w # Determinants and inverse matrices are subject to error due to dropped digits. # Matrix operations are performed individually on each cell, so calculations may require considerable time to complete. # The calculation precision of displayed results for matrix calculations is ± 1 at the least significant digit. # If a matrix calculation result is too large to fit into Matrix Answer Memory, an error occurs. # You can use the following operation to transfer Matrix Answer Memory contents to another matrix (or when Matrix Answer Memory contains a determinant to a variable). MatAns → Mat α In the above, α is any variable name A through Z. The above does not affect the contents of Matrix Answer Memory. # For matrix power calculations, calculation is possible up to a power of 32766. 200509401
