Automatically changing title based on a function input variables names

I made a function that creates a histogram.I want every time i call the function for an input variable 'X' ,the title and the xlabel to change automatically.

For exaple:

• when i i call the function [HISTOGRAM]=hist(apples),then my title should be 'HISTOGRAM apples'
• when i i call the function [HISTOGRAM]=hist(lemons),then my title should be 'HISTOGRAM lemons

The same for xlabel.

Is this possible?

below is the code i have already written.

function [HISTOGRAM]=hist(X)

HISTOGRAM=histogram(X)

title('HISTOGRAM (VARIABLE NAME)')

xlabel('(VARIABLE NAME)')

ylabel('Number of sequence reads')

end

Look at

doc inputname

and see if that gives you any ideas...

You could add a second input argument to your function (and don't call your function hist because that's already taken by a built-in MATLAB function):

my_hist(randn(100),'jackfruit');

function [HISTOGRAM]=my_hist(X,var_name)
HISTOGRAM=histogram(X);
title(sprintf('HISTOGRAM (%s)',var_name))
xlabel(sprintf('(%s)',var_name))
ylabel('Number of sequence reads')
end
