Hi, i just learn about basic/introduction to programming code using Matlab. I have exercise as below and need assistance. Would appreciate of i could get brief explanation/ comment on every line of code/answer.

and table 1 as below :

Table 1 shows the time series of measurements of reaction temperature. Create a MATLAB script to do a following task:- 1. Plot the graph of interpolation data and given data in 2x2 display(1 plot for 1 method), complete with the title and axis label Find the atmospheric pressure at 90 temperature and 60 temperature by using all four types of interpolation method and display the value Relative humidity (%) 99 97.1 95.2 93.3 91.4 89.5 87.6 85.7 83.8 81.9 80 78.1 76.2 74.3 72.4 70.5 68.6 66.7 64.7 62.8 60.9 59 57.1 55.2 53.3 Atmospheric pressure (hPa) 1316.899 1291.574 1266.249 1240.924 1215.599 1190.274 1164.949 1139.624 1114.299 1088.974 1063.649 1038.324 1012.999 987.674 962.349 937.024 911.699 886.374 861.049 835.724 810.399 785.074 759.749 734.424 709.099
