2 values for inputs of a function

If i have a function

example:

function(T,L)=answ(b,c,d)
L= b + c + d
T= 2*L
end

and i have 2 of c which are 25 and 60 1 of b which is 5 and 0 of d

where b c and d have their own equation

How can i input 2 values for c?

In case of a vectorized function (yours is) you can use vector inputs:

b = 5;
c = [25; 60];
d = 0;

[T, L] = answ(b,c,d)


function [T, L] = answ(b,c,d)
L= b + c + d;
T= 2*L;
end

gives vector outputs:

T =

    60
   130


L =

    30
    65

Maybe i didnt explain my self right. Since i have 2 values of c i need L to be example b + c1 + c2 + d but i can have any amount of all 3.

So i can have 3 b and 0 c and 2 d for example.

Example 3 books, 0 carts and 1 desk

function [T,L] = answ(k,am,D,C,B)
L = book(B)  + cart(C) +  desk(D);
T= 2*L + am*4 + k*3;
function[b]=book(B)
b=B*4.2;    
end
function[c]=cart(C)
c=2*C^2;
end
function[d]=desk(D)
d=D*1.30;
end
end

This is what i tried

but when then i tryied to input >>answ(1,3,3,-,2)

for C since i have 2 i didnt know what to enter as value

Maybe working with the sum:

B = 5;
C = [25; 60];
D = 0;
k = 1;
am =1;

[T,L] = answ(k,am,D,C,B)

function [T,L] = answ(k,am,D,C,B)
L = sum(book(B)  + cart(C) +  desk(D));
T= 2*L + am*4 + k*3;
end

function b=book(B)
b=sum(B*4.2);
end

function c=cart(C)
c=sum(2*C.^2); 
end

function d=desk(D)
d=sum(D*1.30);
end

Didnt work

For me it worked. Whats the issue?

Error: File: answ.m Line: 8 Column: 27

Function 'answ' has already been declared within this scope.

Comment out old code or use my in a new script. Copy the whole code and run it.
