Write a program to analyze the cooling of a cup of coffee. Start by asking the user to enter a matrix in the format [a, b; c, d]. The matrix win contain two columns; the first is time in minutes and the second is temperature in degrees Celsius. These pairs of values indicate the actual temperatures of the coffee at the specified times. If the matrix entered does not have at least two rows or does not have exactly two columns, warn the user and ask them to enter a matrix in the correct format until they do it correctly. Next ask the user to enter the room temperature [°C].
Create a table of output showing the time in hours and toe temperature above room temperature m degrees Fahrenheit.
Time must be shown to two decimal places; temperature should be shown as an integer.
- The output statement must be written such that the number of entries in toe matrix could change and the table would still be created correctly
Using the data entered, create a graph with an exponential trendline to project the temperature above room temperature at 30 minutes on a graph.
- The axis limits, grid, axis labels, and title must match exactly to the graph shown. The title is shown in bold, red letters, size 20. Time should be in minutes and temperature above room temperature should be degrees Fahrenheit.
- The markers are open red circles, size 16.
- The line is red dashed format, line width 2.
- Background color on the trendline text is green; font sue is 16.
- The background on the graph is white.
Example:
Enter a matrix of form [a, b; c, d] for time [min], temperature [deg C] of a cup of coffee.
[1, 91; 5, 87.5, 8, 84.9];
Enter the temperature of the room [deg C]: 26
Time (t) [h] | Temp above Room (T) [deg F] |
0.02 | 117 |
0.08 | 111 |
0.13 | 106 |
After the table and graph have been produced, use a menu to ask users if they wish to analyze another set of data, and either repeat or terminate the program as appropriate.

- I’m using this code in MATLAB but for some odd reason every time I run it on MATLAB I keep on getting a different graphs. In the picture that shows two different graphs are from the same code, but I need to it to look like the picture that has one graph. Could you please fix it. To make it look like the picture that has one graph? Here is the code: % Sample data for Diesel and Petrol carPosition = linspace(1, 60, 50); % Assumed positions of cars CO2Diesel = 25 + 5*cos(carPosition/60*2*pi) + randn(1, 50)*5; % Random data for Diesel CO2Petrol = 20 + 5*sin(carPosition/60*2*pi) + randn(1, 50)*5; % Random data for Petrol % Fit polynomial curves pDiesel = polyfit(carPosition, CO2Diesel, 3); pPetrol = polyfit(carPosition, CO2Petrol, 3); % Generate points for best fit lines fitDiesel = polyval(pDiesel, carPosition); fitPetrol = polyval(pPetrol, carPosition); % Plotting the data figure; hold on; scatter(carPosition, CO2Diesel, 'o', 'MarkerEdgeColor', [1 0.5 0]); % Diesel data…arrow_forwardThe Pascal triangle can be displayed as elements in a lower-triangular matrix as shown on the right.
