Can we make the for loop a feedback loop that stops at a certain value?

I'm using a for loop to check the value of a dependent variable based on an independent variable. Is there any way that when it reaches the value I want, the loop stops?
Also, can I specify a range? For example, when the value of the variable falls between 1.90 and 2.10, the loop stops and reports the value of the independent variable.

For the range, an if (link) block would work.
To stop the loop, use the break (link) or return (link) functions, depending on what you want to do.
EDIT — Also consider that MATLAB has a number of optimization functions that can easily do what you want.
For example, using fzero:
f = @(x) x.^2 - 16; % Find ‘x’ Where ‘x^2 = 16’
x = fzero(f, 1)
x =
4.0000
