Project - Data Handling and Interpolation

1. Downloaded the given VI.xlsx exel file,

2. written the programme,

• 1st uses clc and clear all command to clean the workspace and command window.
• then data variables used to read the VI.xlsx file,
• then V variables mentioned as 1st coloumn of exel file and I variable mentioned as 2nd column of exel file,
• figure1 used to plot V vs I curve,
• Iq is mentioned as -17.3:0.1:0.9 mentoned as question as interpolation range,
• Vq1 is written as defult linear interpolation method of V vs I,
• and Vq2 is written as spline interpolation of V vs I,
• figure2 is created to plot defult linear interpolation data,
• figure 3 is created to plot spline interpolation data.
• title given for spline interpolation data.
• Vq1 and Vq2 is written to show output value in command window,
• fileID variable and fopen command used to create a file project_1.txt, and 'w' used to write to the file,
• fprintf command with in fileID , '%4.4f\n', Vq1 and Vq2 used to write the value of Vq1 and Vq2,
• fclose command to close and save the project_1.txt used,
• after run the project_1.m, figure 1 for V vs I curve, figure 2 for defult linear interpolation, figure 3 for spline interpolation and project_1.txt file to interpolation data created.
