plus - Matrix sum of `fi` objects

Syntax

plus(a,b)

Description

plus(a,b) is called for the syntax a + b when a or b is an object.

a + b adds matrices a and b. a and b must have the same dimensions unless one is a scalar value (a 1-by-1 matrix). A scalar value can be added to any other value.

plus does not support fi objects of data type Boolean.

Note For information about the fimath properties involved in Fixed-Point Toolbox calculations, see Using fimath Properties to Perform Fixed-Point Arithmetic and Using fimath ProductMode and SumMode in the Fixed-Point Toolbox User's Guide.

For information about calculations using Simulink Fixed Point software, see the Arithmetic Operations chapter of the Simulink Fixed Point User's Guide.
