Use publish() with input variables for function with input object

Hello,

I want to use the publish() call with a function that has an input object. The only documentation I can find allows you to have a numerical input but not a variable input. This example is given in the documentation

publish('fact.m','codeToEvaluate','fact(5);')
web('html/fact.html')

I want to run the same function but replace "5" with an input variable "x". Is there a way to accomplish this?

x=5
publish('fact.m','codeToEvaluate','fact(x);')
web('html/fact.html')

If I run the above example I get the following warning

"Error using evalin

Argument must be a text scalar."

Hi

I understand that you want to use publish() function with a variable name so this workaround might be of good help to you.

You use string concatenation to create the string with the fact() function that can be passed as a third argument to the publish function.

x = 5;
codeToEvaluate = ['fact(', num2str(x), ');'];
publish('fact.m', 'codeToEvaluate', codeToEvaluate);
web('html/fact.html');

In the above code, we are creating the string “codeToEvaluate” that includes the value of x with function fact().

Thanks
