minus - Matrix difference between `fi` objects

Syntax

minus(a,b)

Description

minus(a,b) is called for the syntax a - b when a or b is an object.

a - b subtracts matrix b from matrix a. a and b must have the same dimensions unless one is a scalar value (a 1-by-1 matrix). A scalar value can be subtracted from any other value.

minus 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.
