how to convert char into text??

hi guys

I have files with same name but different extension numbers

for example

filename='file_';
fileExt='22'
name=[filename,fileExt];

the output name

name='file_22'

but I need the output just as text, I am planning to call function from this output

%  I need the output to like 
name=file_22

any possible ways, thanks

Do you mean that you need to access a variable named file_22 in that statement?

yes... any possibility

You can use str2func command for this purpose.

fun=str2func(name)

By this you will create a function handle and then you may call it by typing

fun(..,..)

[Muhammad RSMY]

still quite confusion, could you please explain how to call it,, thanks after all

[Birdman]

Ok, consider you wrote a function called summing, which sums two numbers.

function y=summing(a,b)
y=a+b;
end

Then, write the following lines:

name='summing';
fun=str2func(name);
y=fun(1,2)

which will result in 3.
