mtimes

Matrix product of fi objects

Syntax

C = mtimes(A,B)

Description

C = mtimes(A,B) is the matrix product of A and B. mtimes(A,B) is called for the syntax A*B when A or B is a fi object.

Note

For information about the fimath properties involved in Fixed-Point Designer™ calculations, see fimath Properties Usage for Fixed-Point Arithmetic and fimath ProductMode and SumMode.

Input Arguments

A,B — Operands

scalars | vectors | matrices | multidimensional arrays

Operands, specified as fi scalars, vectors, matrices, or multidimensional arrays.

• The number of columns in A must be equal to the number of rows in B, unless A or B is a scalar.

• fi objects of data type boolean are not supported.

Data Types: fi
Complex Number Support: Yes

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.

• Variable-size inputs are only supported when the SumMode property of the governing fimath is set to SpecifyPrecision or KeepLSB.

• For variable-size signals, you may see different results between the generated code and MATLAB^®.

  • In the generated code, the output for variable-size signals is computed using the SumMode property of the governing fimath.

  • In MATLAB, the output for variable-size signals is computed using the SumMode property of the governing fimath when both inputs are nonscalar. However, if either input is a scalar, MATLAB computes the output using the ProductMode of the governing fimath.
