MAT
Syntax
MAT dim.array = expr
MAT dim.array = MAT dim.array2
Description
The first form of the UniBasic MAT command assigns new values to all elements of
a dimensioned array based on an expression.
The second form assigns the contents of a dimensioned array to another dimensioned
array.
If you assign a dimensioned array the values of a second dimensioned array, the
assignment proceeds from element to element in consecutive order. The program
assigns the first element of the first array to the first element of the second array, then
assigns the second element to the second element of the second array, and so on. The
two arrays do not have to match in configuration of dimensions, but must contain the
same number of elements. UniData does not alter the second dimensioned array in
the assignment process.
Use the DIM command to dimension all arrays before you assign new values to the
elements. You can place MAT in any looping structure and assign the elements with
a variable or function.
