Hi I have a function "a" called "function x=problem1(a,b,c,d)" I would like to create a function "b" that call function "a" and asign values to (a,b,c,d). Also, the function "b" have to run at least 6 times just with one call.

No, I'm talking about a function to run replace_me 5 times with diferents inputs. Like this:
% code
function problemb
1 try
v=[1 2 3 4];
a=2
b=8
c=6
end
2 try
v=[5 6 7 8];
a=6
c=2
end
3 try
v=[1 2 6 9];
a=2
b=8
c=6
end
In my example, I already define the inputs for each run, so, I just put both .m files together and run the problem one time to have 5 different solutions at once.

Thanks for your answer, one more question When I run your code, the answer is:
% code
ans =
1×3 cell array
[1×5 double] [1×5 double] [1×5 double]
How do I do to show the vectors?

The question is not really clear. I assume that this is very basic and suggest to read the Getting Started chapters to learn the fundamentals of programming. But here a suggestion:
function b
for k = 1:6
a = rand;
b = 17.3;
c = k;
d = a + b + c ^ 2;
x = problem1(a,b,c,d);
disp(x);
end
Now look at the code and explain, what your problem is with any details.

Ok, I will try to explain it better. Supose I have the next code:
% code
function w = replace_me(v,a,b,c)
if nargin < 3
b = 0;
end
if nargin < 4
c = b;
end
w = [];
for k = 1:length(v);
if v(k) == a % if a is found,
w = [w,b,c]; % we insert b and c at the end of the current w
else % otherwise,
w = [w,v(k)]; % we insert the original element of v
end
end
end
I will like to create another function that has the input parameters for "function w = replace_me(v,a,b,c)", but it has to try the code with 5 diferent input options at the same time.

Your existing code already handles the possibility that v will be a vector of length 5. Your existing code has b and c be optional. Are you talking about 5 different a values? If so, then would it be acceptable to just change
if v(k) == a
to
if ismember(v(k), a)
?
