[scilab-Users] Function resize_matrix with hypermatrix

[Mike Page]

Hi,

The hypermatrix is stored as a linear array of data and a vector of
dimensions.  You may be able to do what you want by altering the dimensions.
For example:

-->a=hypermat([2,3,4],[1:24])
 a  =

(:,:,1)

    1.    3.    5.
    2.    4.    6.
(:,:,2)

    7.    9.     11.
    8.    10.    12.
(:,:,3)

    13.    15.    17.
    14.    16.    18.
(:,:,4)

    19.    21.    23.
    20.    22.    24.

-->a.dims=[2 4 2]
 a  =

(:,:,1)

    1.    3.    5.    7.
    2.    4.    6.    8.
(:,:,2)

    9.     11.    13.    15.
    10.    12.    14.    16.

As you see, this just changes the dimensions, but leaves the data the same.

This method cannot be used to extend the size of the data though.

Hope that's helpful,
Mike.

Hello,

Does the function resize_matrix with hypermatrix ? It si a similar function
for hypermatrix ?

I envisage to resize my hypermatrix with this function with redefined 2D sub
matrix and concatenated this 2D matrix to create the new hypermatrix.

Thank you.
