minus, -

Matrix difference between fi objects

collapse all in page

Syntax

C = A-B

C = minus(A,B)

Description

C = A-B subtracts matrix B from matrix A.

minus does not support fi objects of data type boolean.

C = minus(A,B) is an alternate way to execute A-B.

Input Arguments

collapse all

`A` — Input array
scalar | vector | matrix | multidimensional array

Input array, specified as a scalar, vector, matrix, or multidimensional array of fi objects or built-in data types. Inputs A and B must either be the same size or have sizes that are compatible. For more information, see Compatible Array Sizes for Basic Operations.

minus does not support fi objects of data type boolean.

`B` — Input array
scalar | vector | matrix | multidimensional array

minus does not support fi objects of data type boolean.

Extended Capabilities

C/C++ Code Generation
Generate C and C++ code using MATLAB® Coder™.

Usage notes and limitations:

Any non-fi input must be constant; that is, its value must be known at compile time so that it can be cast to a fi object.

HDL Code Generation
Generate VHDL, Verilog and SystemVerilog code for FPGA and ASIC designs using HDL Coder™.

R2021b: Implicit expansion change affects arguments for operators

Starting in R2021b with the addition of implicit expansion for fi times, plus, and minus, some combinations of arguments for basic operations that previously returned errors now produce results.

If your code uses element-wise operators and relies on the errors that MATLAB^® previously returned for mismatched sizes, particularly within a try/catch block, then your code might no longer catch those errors.
