mtlb_sparse
===========

convert sparse matrix



Calling Sequence
~~~~~~~~~~~~~~~~


::

    Y=mtlb_sparse(X)




Arguments
~~~~~~~~~

:X sparse matrix
: :Y sparse matrix in Matlab format
:



Description
~~~~~~~~~~~

`Y=mtlb_sparse(X)` is used to convert `X`, a Scilab sparse matrix, to
Matlab format. `Y` is the a variable with type 7, i.e. `type(Y)` is
equal to 7. This function should be used in mexfiles (a Matlab mexfile
containing sparse matrices can be used only if the Scilab sparse
matrices are converted to that format). The functions `full` and
`spget` work with this format.

Other operations and functions using this format can be overloaded
with Scilab functions using the prefix "%msp". For instance the
function `%msp_p(x)` (see SCI/modules/overloading/macros directory) is
used to display such "type 7" objects.



Examples
~~~~~~~~


::

    X=`sparse`_(`rand`_(2,2)); Y=mtlb_sparse(X);
    Y, `full`_(Y), [ij,v,mn]=`spget`_(Y)
