MATMUL Matrix Multiplication
The MATMUL block computes the matrix multiplication of two inputs matrices.The number of rows of the second matrix must be equal to the number of columns of the first matrix. The output is a matrix where the number of rows is equal to that of the first input matrix and the number of columns is equal to that of the second input matrix.
- 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.
- Multiplication rule (1= * 2= .* )
?
Properties : Type 'vec' of size 1.
