imat_shp/ldivide

Purpose

Termwise divide shape coefficients (s1.\s2).

Syntax

s1.\s2
s.\x
x.\s

Description

The following termwise multiplication operations are possible with imat_shp objects

• Dividing two imat_shp objects causes their ordinates to be divided termwise. The shape node numbers must agree between the shapes being divided. If one of the operands is a single shape (1x1), then its coefficients will be used with 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 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_shp causes the numeric values to be termwise divided into or divided by the shape coefficient values of the imat_shp.

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

Examples

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

s =
3x1 IMAT Shape with the following attributes:
