How do I call another function in the same file from the first function

Hi.

That is my code.

% function file

function [p1,p2,Name1,Name2]= Playerpoint(point1,point2)

point1 = 10; % get the points

point2 = 15;

p1 = point1+10;

p2= point2 +10;

Name1 = name1;

Name2 = name2;

fprintf("The first user %s has %d points\n",Name1,p1);

fprintf("The second user has %d points\n",Name2,p2);

end

function [name1,name2] = Playername(n1,n2)

name1 = n1;

name2 = n2;

end

% driver file

n1 = input('Please enter the first user name: ','s'); % let players enter the names

n2 = input('Please enter the second user name: ','s');

[name1,name2] = Playername(n1,n2);

[p1,p2,Name1,Name2]= Playerpoint(point1,point2);

In my code, i try to create two players and let them get their inital points.

But there are bug Unrecognized function or variable 'name1'.

That is my expected result:

Please enter the first user name: abby

Please enter the second user name: bob

The first user abby has 20 points.

The second user bob has 25 points.

Hi,   

As per my understanding you want to know how to remove the error being generated while running the program. To remove the error, you must define the functions before calling the function. The error is being generated as you are not passing “name1” and “name2” parameters to the “Playerpoint” function. Also, you don’t need to pass “point1 and point 2” as parameters in the “Playerpoint” function as they are being defined inside the function. The following code snippet may help.

%Code Section 
n1 = input('Please enter the first user name: ','s'); % let players enter the names
n2 = input('Please enter the second user name: ','s');
[name1,name2] = Playername(n1,n2);
[p1,p2,Name1,Name2]= Playerpoint(name1,name2);

function [p1,p2,Name1,Name2]= Playerpoint(name1,name2)
    point1 = 10; % get the points
    point2 = 15; 
    p1 = point1+10;
    p2= point2 +10;
    Name1 = name1;
    Name2 = name2;
    fprintf("The first %s user  has %d points.\n",Name1,p1);
    fprintf("The second %s user has %d points.\n",Name2,p2);  
end
function [name1,name2] = Playername(n1,n2)
    name1 = n1;
    name2 = n2;
end
