anynan
Syntax
Description
Examples
Determine If Vector Contains NaN
Create a row vector A
. Determine if at least one element of A
is NaN
.
A = 0./[-2 -1 0 1 2]
A = 1×5
0 0 NaN 0 0
TF = anynan(A)
TF = logical
1
anynan
returns logical 1
(true
) because at least one element of A
is NaN
.
Create another row vector B
. Determine if at least one element of B
is NaN
.
B = [-2 -1 1 2]/0
B = 1×4
-Inf -Inf Inf Inf
TF = anynan(B)
TF = logical
0
anynan
returns logical 0
(false
) because no element of B
is NaN
.
Determine If Matrix Contains NaN
Create a matrix and determine if at least one of its elements is NaN
.
A = [0 0 3;0 0 3;0 0 NaN]
A = 3×3
0 0 3
0 0 3
0 0 NaN
TF = anynan(A)
TF = logical
1
Determine If Array Contains NaN
Create a 3-D array and determine if at least one of its elements is NaN
.
A(:,:,1) = [2 1; 3 5]; A(:,:,2) = [0 0; 0 Inf]; A(:,:,3) = [-2 9; 4 1]
A = A(:,:,1) = 2 1 3 5 A(:,:,2) = 0 0 0 Inf A(:,:,3) = -2 9 4 1
TF = anynan(A)
TF = logical
0

Extended Capabilities
Tall Arrays
Calculate with arrays that have more rows than fit in memory.
The
anynan
function fully supports tall arrays. For more information,
see Tall Arrays.
C/C++ Code Generation
Generate C and C++ code using MATLAB® Coder™.
GPU Arrays
Accelerate code by running on a graphics processing unit (GPU) using Parallel Computing Toolbox™.
The anynan
function
fully supports GPU arrays. To run the function on a GPU, specify the input data as a gpuArray
(Parallel Computing Toolbox). For more information, see Run MATLAB Functions on a GPU (Parallel Computing Toolbox).
Distributed Arrays
Partition large arrays across the combined memory of your cluster using Parallel Computing Toolbox™.
This function fully supports distributed arrays. For more information, see Run MATLAB Functions with Distributed Arrays (Parallel Computing Toolbox).
