Hello,
I have an equation:
((w^2)/g) = k*tanh(k*d)
and I need to solve for k, but I have 50 w values and I am not sure how to solve for 50 k values. I know how to solve for it if only have one w value, but not for 50. If some one could please help me out that would be great. Thanks.
w = w = 0.188:0.021363:1.256

Use a for-loop to loop through your w values.
for ii = 1:numel(w)
solve_with_w(ii)
end

The same way you normally do? You want one k value for each w value correct? Otherwise what are you trying to do? Come up with a best k for all w? Add more detail to your question

How does this solve for "k" and when use that code it says it doesn't like "solve_with_w(ii)

so I have 50 w values and for each w value I need a corresponding k value using the equation
((w^2)/g) = k*tanh(k*d)
I need to solve for 1 k value using a corresponding w value
so end the end I will have 50 w values and each one of those will have their on k value (which means I will have 50 k values in the end)
