Description

The RESHAPE block changes the dimensions of a matrix or a vector to another dimensions specified by the user in the "output size desired" label. The output size must be less 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 xcos 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]
