imat_fn/times

Purpose

Termwise multiply ordinates (f1.*f2).

Syntax

f1.*f2
f.*x

Description

The following termwise multiplication operations are possible with imat_fn objects:

• Multiplying two imat_fn objects causes their ordinates to be multiplied termwise. If one of the operands is a single function (1x1), then its ordinate will be multiplied by all elements in the other operand. If both operands are function arrays, they must have the same dimensions. The data attributes of the result of a termwise multiplication will be taken from the left operand, except that ordinate data types (i.e., units exponents) will correctly reflect the combination of the two operands.

• Multiplying a numeric array or scalar times an imat_fn causes the numeric values to be termwise multiplied into the ordinate values of the imat_fn.

Examples

>> f=imat_fn(3,'ordinate',reshape(1:15,5,3))

f =
3x1 IMAT Function with the following attributes:
Record Name          FunctionType     AbscissaSpacing  NumberElements
-------------------- ---------------- ---------------- ----------------
1_(1X+,1X+)          Time Response    Even             5
2_(1X+,1X+)          Time Response    Even             5
3_(1X+,1X+)          Time Response    Even             5

>> f.ordinate

ans =
     1     6    11
     2     7    12
     3     8    13
     4     9    14
     5    10    15

>> g=f.*f; g.ordinate

ans =
     1    36   121
     4    49   144
     9    64   169
    16    81   196
    25   100   225

>> g=g.*g(1); g.ordinate

ans =
           1          36         121
          16         196         576
          81         576        1521
         256        1296        3136
         625        2500        5625
