Josh - FOR may not be aligned with its matching end is a warning only and can be ignored for the moment. In fact, once you resolve the errors, this warning message will disappear. With line
fun = @x x/(1-x) * sqrt((2p)/(2+x)) - k;
there is a Parse error at x: usage might be invalid MATLAB syntax. For anonymous functions, you need to wrap the input variable(s) in parentheses like
fun = @(x) x/(1-x) * sqrt((2p)/(2+x)) - k;
This will lead to another error message invalid syntax at p. What is the intent here? Do you wish to multiply p by 2 or divide or ..? You must supply the correct operator.
Once that has been corrected, there will be another parse error at the line
for iter 1:50
You are missing an equals sign to indicate which values the indexing variable iter is meant to take on
for iter=1:50
And that is it. The warning message disappears and you should be good to execute the code....except for the
Subscript indices must either be real positive integers or logicals.
Error in xxxx (line 27)
x1 (p,:) = root;
which is telling you that your p is not a real positive integer. In this case it is a double since p is the indexing variable of the outer for loop
for p = 1:.2:4
What are you trying to assign to x1 and why are you trying to use p? What is intended here?
