imat_shp/times

Purpose

Termwise multiply shape coefficients (s1.*s2).

Syntax

s1.*s2
s.*x

Description

The following termwise multiplication operations are possible with imat_shp objects:

• Multiplying two imat_shp objects causes their shape coefficients to be multiplied termwise. The shape node numbers must agree between the shapes being multiplied. If one of the operands is a single shape (1x1), then its coefficients will be multiplied by all elements in the other operand. If both operands are shape 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_shp causes the numeric values to be termwise multiplied into the shape coefficient values of the imat_shp.

Examples

>> s=imat_shp(3,'shape',reshape(1:18,6,3))

s =
3x1 IMAT Shape with the following attributes:
Row Frequency           Damping             NumberNodes
--- ------------------- ------------------- -------------------
1   1                   0.01                2
2   1                   0.01                2
3   1                   0.01                2

>> s.shape

ans =

     3     9    15
     4    10    16
     5    11    17

>> t=s.*s; t.shape
