The following table gives temperature data in *C as a function of time of day and day of the week at a specific location.
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.
Solutions
Expert Solution
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

Collins temperature data (Data file: ftcollinstemp) The data file
gives the mean temperature in the fall of each year, defined as Sep-
tember 1 to November 30, and the mean temperature in the following
winter, defined as
December 1 to the end of February in the following calendar year,
in degrees Fahrenheit, for Ft. Collins, CO (Colorado Climate
Center, 2012). These data cover the time period from 1900 to 2010.

What is the temperature on the winter day?
On a warm summer day (33 ∘C), it takes 4.70 s for an echo to return from a cliff across a lake. On a winter day, it takes 5.10 s . The speed of sound in air is v≈(331+0.60T)m/s, where T is the temperature in ∘C.
