MATBKSL:left matrix division
The MATBKSL block outputs the left matrix division. It is a solution to A*x=B. The higher input is the A matrix, the lower one is the B matrix, and the output is x. If A is an M-by-N1 matrix, B must be a M-by-N2 where N1 and N2 can be different or equal. The output x is a N1-by-N2 matrix.
The equivalent of MATBKSL is the backslash operator 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 Scicos will print the message "Datatype is not supported".
Properties : Type 'vec' of size 1.
A=[1 7 3;23 32 29]
B=[21 18;13 10]
then the result of the A*x=B equation is (A\B):
x=[-4.504 -3.922;3.643 3.132;0.000 0.000]
