Project - Data Handling and Interpolation

Ans

Here we have used the commond 'interpl' for the interpolation . the output xql is put to the text file called 'interpolation'

Code for interpolation

% open the text file to write the output

% define a variable x from excel file

% define a variable y from excel file

% define the range for interpolation

% interpolation

% plotting the interpolation

% print the output xq1 to the file transfer

fileID = fopen('interpolation.txt', 'w');

x = ImAmp;

y = VVolt;

xq = [-17.3:0.1:0.9];

xq1 = interp1(y,x,xq);

figure(1);

ploot(x,y,'o',xq,xq1,':');

grid;

fprintf(fileID,'%f','xq1');
