Syntax

[pos, v] = steepestDescent(sF) % the position where the minimum is attained

[pos, v] = steepestDescent(sF,'numLocal',5) % the 5 largest local minima

% with all options
[pos, v] = steepestDescent(sF, 'startingnodes')

Output

`v`	`double`
`pos`	`vector3d`

Options

`iterMax`	`number of iterations`
`numLocal`	`number of peaks to return`
`startingNodes`	`vector3d`
`tolerance`	`minimum distance between two peaks`
`resolution`	`minimum step size`
`maxStepSize`	`maximum step size`
