You are standing in a few inches of sea water on a beach.

You are wondering whether the high tide is coming soon or it has just passed.

Therefore, you will write a code in MATLAB to analyze following data.

You followed the sequence of water lines left by several swash of waves.

The data array A contains the distances the water traveled past your feet during each upward swash of waves.

Your code will return 1 if the high tide is coming soon.

Your code will return 0 if the high tide has just passed.

Is there a reference, that I can use, for predicting high/low tide from the water line height? I don't want to construct a solution based on the test suite data.

We can use derivatives for predicting the high tide (diff) when we can assume that a function is increasing or decreasing (even with some noise).
