imat_fn/ldivide

Purpose

Termwise divide ordinates (f1.\f2).

Syntax

f1.\f2
f.\x
x.\f

Description

The following termwise multiplication operations are possible with imat_fn objects:

• Dividing two imat_fn objects causes their ordinates to be divided termwise. If one of the operands is a single function (1x1), then its ordinate will be used with 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 division 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.

• Dividing a numeric array or scalar and an imat_fn causes the numeric values to be termwise divided into or divided by the ordinate values of the imat_fn.

A termwise left division operation in MATLAB is the same as a right division with the operands switched.

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+1; g.ordinate

     3     8    13
     4     9    14
     5    10    15
     6    11    16

>> h=g.\f; h.ordinate
