A research team collected temperature data from two lakes $($Lake $x$ and Lake $Y)$ over a period of $10$ days. The temperatures, measured in degrees Celsius, are given in the table below:

$\backslash$table$[[$Day$,$Temp in Lake X$,$Temp in Lake Y$],[1,57,55],[2,59,60],[3,61,63],[4,62,65],[5,64,67],[6,66,66],[7,62,64],[8,60,61],[9,58,58],[10,55,56]]$

Determine the number of days when the temperature in Lake $x$ was at or above $60$ degrees Celsius.

Identify the days when the temperature in Lake $x$ was higher than that in Lake Y$.$

Write a MATLAB code that computes the temperature in Lake $x$ on the days when it was greater than or equal to the temperature in Lake Y$.$
