Matrix division
The MATDIV block outputs the right matrix division. It is a solution to x*B=A. The higher input is the A matrix, the lower one is the B matrix, and the output is x.
If A is an M1xN matrix, B must be a M2xN where M1 and M2 can be different or equal. The output x is a M1xM2 matrix.
The equivalent of MATDIV is slash (/) in Scilab.
Datatype(1=real double 2=Complex)
It indicates the type of the output. It support only the two types double (1) and complex (2). If we input another entry in this label Xcos will print the message "Datatype is not supported".
Properties : Type 'vec' of size 1.
A=[1 7 3;23 32 29] B=[21 18 34;13 10 19;11 54 36] then the result of the x*B=A equation is (A/B): x=[-0.475 0.712 0.156;-4.350 8.381 0.491] |  |  |
