Another experiment provided the following set of data:

Table $2$: Experimental data

Use the forward difference approximation to compute $f^{\text{'}}(2\mathrm{.}36),$ and the central

difference approximation to compute $f^{\text{'}}(2\mathrm{.}37)$ and $f^{\text{'}\text{'}}(2\mathrm{.}37)$ from the data.

Write a Matlab code to compute $f^{\text{'}}(x)$ from the data and plot the $x-f^{\text{'}}$ curve.
