MATLAB- for loop and interation

Hi
I'm using an interation method to solve for 3 variables in 3 non-linear equations. I would like to find out, how the 3 variables change, when I change a parameter in the 3 equations. Let's assume the parameter runs from 1 to 5 (1:1:5).

The iteration looks like this:
x0 = [1; 1; 1]; % Make a starting guess at the solution
options=optimset('Display','iter'); % Option to display output
[x,fval] = fsolve('file_that defines_the_3_functions',x0,options) % Call optimizer, where x is vector of the 3 variables

Preferable I would like to save the results in a 3*5 matrix, where n is the number variables and 5 the number of different parameters.

In the last sentence, I meant "where 3 is the number of variables...", not n.

Is this question not clear? Please let me know, when I need to clarify the question. I have the same problem!!!!!
I know this was posted 3 years ago, so if you managed to solve the problem can you please share the solution???
Thank you!!!
