Can argument validation check if size is at least some value?

I understand that the arguments block can check if an argument is exactly a given size, but is there a way to check if an array is at least a certain size? (without using a custom validation function)

Example

arguments
    a (:,4) % must be exactly 4 columns
    b (:, >=4) % must have at least 4 columns
end

No. You will need to create your own custom validation function. Use the mustBeEqualSize example on this documentation page as a model.

Answer 2

[Torsten]

b = 1:5;
v = size(b,2) >= 4

v = logical
   1

b = 1:3;
v = size(b,2) >= 4

v = logical
   0

how do you use that in an arguments block. See https://www.mathworks.com/help/matlab/ref/arguments.html
