How to "extract" a variable name to a string ?

Hi

I need to make a lot of plot to debug my code.

For this purpose, I have a function that plots the vector I give her as input.

I would like to be able to get the name of the variable I am plotting, extract it in a string and use it to title my plot.

How can I do this in Matlab ?

Thank you for your help.

Illustrative, oversimplified example :

function plottingFct(quantityToPlot)
% Simplified example of what I would like to do

figure
plot(quantityToPlot)

NameOfVariableIPlot=ExtractNameOfVariable(quantityToPlot); % How can I do this ?

title(NameOfVariableIPlot);
end

Try the following:

myvar = 1;
get_myvar_name = @(x) inputname(1);
get_myvar_name(myvar)

Answer 2

[Walter Roberson]

NameOfVariableIPlot = inputname(1);

Note that this will be empty if the input was an expression.

Answer 3

Try this: inputname()

Example:

function myfun2(a,b,c)
for m = 1:nargin
    disp(['Calling variable ' num2str(m) ' is ''' inputname(m) '''.'])
end

Use the inputname (link) function:

function plottingFct(quantityToPlot)
% Simplified example of what I would like to do
figure
plot(quantityToPlot)
NameOfVariableIPlot=inputname(1); % How can I do this ?
title(NameOfVariableIPlot);
end

Qwerty = rand(1, 10);

plottingFct(Qwerty)
