I used a trivial function
function a = invalid_fun (a)
a = a .+ 1;
end
Then ...
addpath ('~/Documents/MATLAB/a')
matlab>p = meta.package.fromName('pack')
p =
package with properties:
Name: 'pack'
ClassList: [0x1 meta.class]
FunctionList: [1x1 meta.method]
PackageList: [0x1 meta.package]
ContainingPackage: []
matlab>fcn = p.Functions{1}
fcn =
method with properties:
Name: 'invalid_fun'
Description: ''
DetailedDescription: ''
Access: 'public'
Static: 0
Abstract: 0
Sealed: 0
Hidden: 0
InputNames: {'rhs1'}
OutputNames: {'lhs1'}
DefiningClass: []
matlab>fcn()
ans =
method with properties:
Name: 'invalid_fun'

DetailedDescription: ''

And I get no error. Have I done something wrong? I'm not familiar with the
meta.packages. How may I actually call the function?
