Array variable

Example(s)

When an array variable is used to describe a dimensioned array, it must be used with a subscript to indicate the specific variable descriptor in the array:

a(10) or a(n)

Otherwise it must be used in a mat statement to indicate all elements in the array:

mat a = ''

This sets every variable in the array a to null.

matread afrom...

This reads an item and parses the attributes to the dimensioned array a.
