We're trying to create a wave height prediction model to predict swell size at a local beach the variables are as follows.
the following figures come from a wave buoy situated some 15 miles off the coast on an hourly basis
I need a little help with an array we have it in excel buy no idea how to write it in php
wave period in seconds
wave height ft

Period Factor
4.5 0
8 0.5
12.5 1


Example:
Given Period this predicts the factor (sec) = 8secs
Given Wave height (ft) = 13ft
Factor Prediction = 0.458549223
Wave height prediction = 5.961139896

Cheers

Lee

Period Space Factor
4.5 Space 0
8 Space 0.5
12.5 Space 1

You didn't really ask a question.

A two dimentional array works like this:
