Description

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

Creation

Description

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

Note

If arguments includes name-value arguments, use name=value syntax to avoid syntax errors. For more information, see Name=Value in Function Calls

example

Input Arguments

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:
>> hello("world")
