Now im facing

Error: Undefined function or variable n

the value n is actually i get it from the other file that prompt user to enter num of patients

n = input('Enter number of patients : ');

both files are located in the same file and the matlab is also opening the current file that located both files named start.

I also have try adding

n = p;

in the choiceThree file for trying to use a variable that has not been defined before this line of code executes. But the ouput still show out

Error: Undefined function or variable p

By the way, both files i got write

function output = start

in start file and

function output = choiceThree(n);

in choiceThree file

We need to see the innards of both functions to really know what's wrong.

I also have try adding n = p

The error message says that p is undefined. Therefore, you should be doing p=n.
