numsamples

(To be removed) Number of samples in neural network data

numsamples will be removed in a future release. For more information, see Transition Legacy Neural Network Code to dlnetwork Workflows.

For advice on updating your code, see Version History.

Syntax

numsamples(x)

numsamples(x) takes neural network data x in matrix or cell array form, and returns the number of samples.

If x is a matrix, the result is the number of columns of x.

If x is a cell array, the result is the number of columns of the matrices in x.

This code calculates the number of samples represented by matrix data:

x = [1 2 3; 4 7 4]
n = numsamples(x)

This code calculates the number of samples represented by cell data:

x = {[1:3; 4:6] [7:9; 10:12]; [13:15] [16:18]}
n = numsamples(x)
