MATRESH Matrix Reshape

Palette

Matrix - Matrix operation palette

Description

The RESHAPE block changes the dimensions of a matrix or a vector as specified by the user in the "output size desired" label. The output size must be less than or equal to the input size.

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 Scicos will print the message "Datatype is not supported".
Properties : Type 'vec' of size -1.
input size
It indicates the size of the input matrix.
Properties : Type 'vec' of size -1.
output size desired
It indicates the desired output's size.
Properties : Type 'vec' of size -1.

Example

u=[1 2 3 4;5 6 7 8]
When the output desired is [1;6] the output is:
y=[1 2 3 4 5 6]
