Secant method for finding the root of a univariate, scalar-valued function.
x = secant_method(f,x0)
x = secant_method(f,x0,opts)
[x,k] = secant_method(__)
[x,k,x_all] = secant_method(__)
x = secant_method(f,x0,opts) does the same as the syntax above, but allows for the specification of optional solver parameters.
opts is a structure with the following fields:
k_max→ maximum number of iterations (defaults to 200)
return_all→ returns estimates at all iteration if set to
TOL→ tolerance (defaults to )
[x,k] = secant_method(__) also returns the number of iterations (
k) performed of the secant method.
[x,k,x_all] = secant_method(__) does the same as the previous syntaxes, but also returns an array (
x_all) storing the root estimates at each iteration. This syntax requires that
opts.return_all be set to true.
