matlab.lang.correction.AppendArgumentsCorrection class

Package: matlab.lang.correction

Correct error by appending missing input arguments

Description

Use AppendArgumentsCorrection objects in functions that throw an MException object. MException uses AppendArgumentsCorrection instances to display suggestions for missing input arguments.

Creation

Description

example

aac = matlab.lang.correction.AppendArgumentsCorrection(arguments) creates a correction that suggests appending input arguments to the function call that threw the MException object.

Input Arguments

expand all

Suggested arguments, specified as a string or character vector, or a cell array of character vectors.

Examples

collapse all

The function hello requires one input argument. Add a suggested input argument "world" to the error message.

function hello(audience)
if nargin < 1
    aac = matlab.lang.correction.AppendArgumentsCorrection('"world"');
    error(aac, 'MATLAB:notEnoughInputs', 'Not enough input arguments.')   
end
fprintf("Hello, %s!\n", audience)
end

Call the function without an argument.

hello
Error using hello (line 4)
Not enough input arguments.

Did you mean:
