numel

Number of data elements in fi array

Syntax

Description

example

n = numel(A) returns the number of elements, n, in fi array A.

Using numel in your MATLAB® code returns the same result for built-in types and fi objects. Use numel to write data-type independent MATLAB code for array handling.

Number of Elements in 2-D fi Array

Create a 2-by-3- array of fi objects.

X = fi(ones(2,3),1,24,12)
X = 

     1     1     1
     1     1     1

          DataTypeMode: Fixed-point: binary point scaling
            Signedness: Signed
            WordLength: 24
        FractionLength: 12

numel counts 6 elements in the matrix.

n = numel(X)

n =

   6

Number of Elements in Multidimensional fi Array

Create a 2-by-3-by-4 array of fi objects.

X = fi(ones(2,3,4),1,24,12)

X = 

(:,:,1) =
     1     1     1
     1     1     1
(:,:,2) =
     1     1     1
     1     1     1
(:,:,3) =
     1     1     1

(:,:,4) =
     1     1     1
     1     1     1

          DataTypeMode: Fixed-point: binary point scaling
            Signedness: Signed
            WordLength: 24
        FractionLength: 12

numel counts 24 elements in the matrix.

n = numel(X)

n =

   24
