The question is like this,
I have the formula for the theortical deflection d(t) that depends on four parameters(u,v,x,y) that have a specific range ( let it be theoretical deflection)
along with these, I have six measured deflections d(m) at six different points.
So, I need a GA
where the function is the root square mean of the sum of error in each deflection.
i.e., Where the outcome should have a single value for every parameter so that the error should be minimized and have exact or nearby value to measured deflection.

Why there are no u, v, x and y in formula?

No No formula

No, Constant value need to be find out from theoritical deflection.

There are many ways to solve such model-fitting problems. See these examples:
You can always use ga instead of fminsearch or fminunc, though I am not sure why you would want to.

Sir,
If these question were solved by using fminsearch I had used it earlier. It's my research work that's why i can't explain here. But this example is just a protype of what I want. So if you can help me to solve I will be highly obliged to you.
