Operands:
S: Matrix source device D: Operation result n: Array length
Explanations:
1. Range
of
n: K1 ~ K256
2.
S designates KnX, KnY, KnM and KnS; D designates KnY, KnM and KnS.
3.
SA/SX/SC can designate n = 4. EH/EH2/SV can designate n
4
≦ .
4.
See the specifications of each model for their range of use.
5.
S performs an inverse matrix operation according to the array length n. The result is stored in D.
Program Example:
When X0 = On, the 3 arrays of 16-bit registers D0 ~ D2 perform a matrix inverse operation. The result will be stored in
the 3 arrays of 16-bit registers D20 ~ D22.
