fInverseBisection

Invert a monotonic function by vectorized bisection.

Developer documentation: this item describes internal implementation details.

Declaration

 y = fInverseBisection(f,x,yMin,yMax,tol)

Parameters

• f monotonic function handle to invert
• x target values
• yMin lower search bound
• yMax upper search bound
• tol termination tolerance

Returns

• y approximate inverse values satisfying f(y) = x
