Description
The MATDIAG block create a diagonal matrix from a 1D vector. If the input is a Mx1 vector than the output is an MxM matrix.
The equivalent function of MATDIAG in Scilab is diag(vm) with vm a column vector.
Dialog box
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.
Example
if the input of the block is U=ones(5,1) then the output is: y=[1 0 0 0 0;0 1 0 0 0;0 0 1 0 0;0 0 0 1 0;0 0 0 0 1]
