In matlab how do i assign a certain value in the matrix to be changed depending on which sphere option is chosen in the menu then also display it for both volume and specific gravity when printed.

here is the question:

most materials expand as their temperature increases. one way to quantify this is with the volumetric coefficient of thermal expansion (α) [inverse kelvins, k-1]. to calculate the change in volume of an object, you can use :

∆v = α v ∆t

where ∆t is the change in temperature, and v is the initial volume. thus the new volume after a temperature change is the initial volume plus ∆v.

part a: create the variable sphdata containing the matrix shown:

0.9 51 101

1.7 42 88.1

1.5 87 133

0.8 54 76.2
