Description

i. A standard expression of matrix is Mat A[ ] which also can be used in Casio Basic.

ii. C.Basic provides an extended expresison using a small letter for matrix, like Mat a[ ]. 

iii. C.Basic provides a shorter expression for matrix, like A[ ], a[ ], &A[ ] or $a[ ].

iv. Be carefle about using tis abbreviated expression.  
     Instead of following standard expression;
    {<row>,<column>}→Dim Mat A 
    [[<E₁₁>,<E₁₂>,...][<E₂₁,E₂₂>,...]...]→Mat a.
    Mat A→Dim Mat A.x (x = p, v, b, l, f)

   those below cannot be used;
     {<row>,<column>}→Dim A
    [[<E₁₁>,<E₁₂>,...][<E₂₁>,<E₂₂>,...]...]→a.
    A→Dim A.x (x = p, v, b, l, f)

Note

Example 1

    [[1,2,3,4][5,6,7,8]]→Mat A.b
    Locate 1,1,ElmSize(A)
    Mat A→Dim Mat A.w
    Locate 1,2,ElmSize(A) 

This code display as follows;

    8
    16

The first and third line cannot be converted to abbreviated expression. But the second and fourth line use shorter expresison of Mat A.
