Function argument validation is a way to declare specific restrictions on function arguments. Using argument validation you can constrain the class, size, and other aspects of arguments without writing code in the body of the function to perform these tests. ...
If you call the function with a vector that contains nonnumeric values, themustBeNumericvalidation function throws an error. a = ["1""3""5"]; [m,s] = twoStats(a) Error using twoStats Invalid argument at position 1. Value must be numeric. ...
Does MATLAB have a a built-in argument validation function to check if the input to a function (e.g. an array) is uniform? I am looking at the built-in argument validation functions listed on the page, "Argument Validation Functions": ...
%% Function argument validation arguments %% @Required parameters: a(1,1) {mustBeInteger, mustBePositive} b(1,1) {mustBeInteger, mustBePositive} %% @Optional parameters: options.n_bar(1,1) {mustBeInteger, validate_n_bar(options.n_bar, a, b)}= a*b*...
Use function argument validation in MATLAB to declare specific restrictions on function input arguments. You can constrain the class, size, and other aspects of function input values without writing code in the body of the function.
Function with Argument Validation Define a function that restricts input to a numeric vector that contains no Inf or NaN elements. function [m,s] = stat3(x) arguments x (1,:) {mustBeNumeric, mustBeFinite} end n = length(x); m = avg(x,n); s = sqrt(sum((x-m).^2/n)); end...

The specific name-value argument validation overrides the validation defined by class for the individually specified property name. For example, the following function defines name-value arguments as the properties of the matlab.graphics.chart.primitive.Bar class. The function also overrides the propert...

function y = awgn(varargin) %AWGN Add white Gaussian noise to a signal. % Y = AWGN(X,SNR) adds white Gaussian noise to X. The SNR is in dB. % The power of X is assumed to be 0 dBW. If X is complex, then % AWGN adds complex noise. ...
