Example: This example creates a 2x2 matrix named M0 and stores to one of its
elements.
BYTE mName[] = {0,'m','0',0};
/* create a 2x2 matrix of zeros on the estack */
push_ushort_to_integer( 2 );
push_newmat( top_estack, top_estack );
/* Store matrix created with push_newmat to 'M0' */
VarStore( mName+3, STOF_ESI, 0, top_estack );
/* Store 1.234 to M0[2,1] */
push_Float( 1.234 );
VarStore( mName+3, STOF_ELEMENT, 0, top_estack, 1u, 2u );
