Question

The following table gives temperature data in *C as a function of time of day and day of the week at a specific location. Data are missing for the entries marked with a question mark (?). Use linear interpolation with MATLAB to estimate the temperature at the missing points.

Answer 1

Directly using the inbuilt function interpl() in MATLAB to find the values of missing data

%code to interpolate the values

clc
Tues = [15 14 15 18];%data given
x = interp1([1 3 4 5],Tues,2); %2 shows here the the 2nd place needs to be find

Thurs = [16 11 15 20];
y = interp1([1 2 4 5], Thurs,3);

 

Answer :

x = 14.5

  y = 13

x = 14.5

  y = 13
