imat_fn/plus

Purpose

Add ordinates (f1+f2).

Syntax

f1+f2
f+x
x+f

Description

The following addition operations are possible with imat_fn objects:

• Adding two imat_fn objects causes their ordinate values to be added. If one of the operands is a single function (1x1), then its ordinate will be added to 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 an addition operation will be taken from the left operand. No checking is performed to assure that the ordinate attributes of the two operands are consistent.

• Adding a numeric array or scalar to an imat_fn causes the numeric values to be added to 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     OrdNumDataType   NumberElements
-------------------- ---------------- ---------------- ----------------
1_(1X+,1X+)          Time Response    Unknown          5
2_(1X+,1X+)          Time Response    Unknown          5
3_(1X+,1X+)          Time Response    Unknown          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 =
     2    12    22
     4    14    24
     6    16    26
     8    18    28
    10    20    30

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

    16    26    36
