Example To determine the absolute value of the following matrix :
Matrix A =
1–2
–3 4
K6(g)4(NUM)1(Abs)
K2(MAT)1(Mat)aAw
• Determinants and inverse matrices are calculated using the elimination
method, so errors (such as dropped digits) may be generated.
• 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.
