Is there any way to see if the functions I am using in a script/code are included in toolboxes or in the basic Matlab ?

Is there any way to see if the functions I am using in a script/code are included in toolboxes or in the basic Matlab ?

The best would be to get a list of functions that come from toolboxes and the toolbox's name just beside.

You can use which, but you will have to extract the information (Though it might not give the full toolbox name)

%signal processing toolbox
m=which('chirp','-all')

m = 1×1 cell array
    {'/MATLAB/toolbox/shared/siglib/chirp.m'}

%inbuilt
n=which('ismember','-all')

n = 79×1 cell array
    {'/MATLAB/toolbox/matlab/ops/ismember.m'                               }
    {'/MATLAB/toolbox/matlab/ops/@cell/ismember.m'                         }
    {'ismember is a built-in method'                                       }
    {'ismember is a built-in method'                                       }
    {'/MATLAB/toolbox/matlab/codetools/@mtree/ismember.m'                  }
    {'/MATLAB/toolbox/matlab/datatypes/categorical/@categorical/ismember.m'}
    {'/MATLAB/toolbox/matlab/datatypes/tabular/@tabular/ismember.m'        }
    {'/MATLAB/toolbox/matlab/datatypes/datetime/@datetime/ismember.m'      }
    {'/MATLAB/toolbox/matlab/datatypes/duration/@duration/ismember.m'      }
    {'ismember is a built-in method'                                       }
    {'ismember is a built-in method'                                       }
    {'ismember is a built-in method'                                       }
    {'ismember is a built-in method'                                       }
    {'ismember is a built-in method'                                       }
    {'ismember is a built-in method'                                       }
    {'ismember is a built-in method'                                       }
    {'ismember is a built-in method'                                       }
    {'ismember is a built-in method'                                       }
    {'ismember is a built-in method'                                       }
    {'ismember is a built-in method'                                       }
    {'ismember is a built-in method'                                       }
    {'ismember is a built-in method'                                       }
    {'ismember is a built-in method'                                       }
    {'ismember is a built-in method'                                       }
    {'ismember is a built-in method'                                       }
    {'ismember is a built-in method'                                       }
    {'ismember is a built-in method'                                       }
    {'ismember is a built-in method'                                       }
    {'ismember is a built-in method'                                       }
    {'ismember is a built-in method'                                       }

%symbolic toolbox
p=which('syms','-all')

p = 1×1 cell array
    {'/MATLAB/toolbox/symbolic/symbolic/syms.m'}

%inbuilt
q=which('hypot','-all')

q = 7×1 cell array
    {'built-in (/MATLAB/toolbox/matlab/elfun/@double/hypot)'   }
    {'built-in (/MATLAB/toolbox/matlab/elfun/@single/hypot)'   }
    {'hypot is a built-in method'                              }
    {'hypot is a built-in method'                              }
    {'/MATLAB/toolbox/parallel/gpu/@gpuArray/hypot.m'          }
    {'/MATLAB/toolbox/parallel/parallel/@codistributed/hypot.m'}
    {'/MATLAB/toolbox/symbolic/symbolic/@sym/hypot.m'          }

As you can see, functions which are a part of a toolbox return a 1x1 cell array.

if isequal(size(p),[1 1])
    %extract the name of the toolbox
end

@Sim, or just go to MATLAB Documentation (mathworks.com) and start typing the command and you will get a drop-down as you type showing them (if you copy and paste in the drop-down doesn't happen so you have to hit enter to see the seach returns but I usually just backspace away the last character to get the drop-down):

thanks a lot for your comments!! :-)

Answer 1

Hello,

There is a function for that dependencies.toolboxDependencyAnalysis, however it doesn't return the name of the function which requires the particular toolbox.

[Jeffrey Clark]

@Sim and @Mario Malic, this is not an answer if you don't have Simulink (uless you are trying to see if you have Simulink :)

names = dependencies.toolboxDependencyAnalysis({'fillSpace5.m'})
'dependencies.toolboxDependencyAnalysis' requires Simulink.

[Mario Malic]

This works properly if you have Simulink. I think this function should be moved to base MATLAB package.

thanks a lot for your comments!! :-)
