Project - Data Handling and Interpolation

Aim:

To make the MATLAB program for interpolation data analysing

Objective:

In a laboratory experiment, data of voltage and current has been recorded and the same is attached in perform the interpolation in the range of -17.3:0.1:0.9. Generate the interactive plot for the interpolated data and store them file.

Matlab program:

plot(V Volt,I Amp,'-ob','MarkerFacecolor','r','linewidth',3);
VV = interpl(VVolt,ImAmp)
VVolt=-17.3:0.1:0.9;
xlabel('voltage');
ylabel('current');

Output:

A =

• -17.3000 -28.0000
  -17.1000 -24.0000
  -17.0000 -19.0000
  -16.8000 -14.0000
  -16.5000 -9.0000
  -16.0000 -6.0000
  -15.0000 -4.0000
  -14.0000 -3.0000
  -12.0000 -2.0000
  -10.0000 -1.3000
  -8.0000 -1.0000
  -5.0000 -0.6000
  -2.0000 -0.3000
  -0.2000 -0.1000
  0.0900 0
  0.1900 0
  0.2700 0
  0.3900 0.0100
  0.4300 0.0300
  0.5000 0.1700
  0.5500 0.4200
  0.6000 1.2300
  0.6200 1.9900
  0.6500 3.9100

Interpolation data using :

fileidl=fopen('C:\Users\rdram\Downloads.xlsx','r')
fileid=fopen('C:\Users\rdram\Downloads.txt','w')
VV =[-17.2 -17.1 -13.8 -13.5 -13.0 -12.5 -11 -9 -5.76 -6 -1 0.11 0.25 0.5 0.61];
VVolt=-17.3:0.1:0.9;
c=interpl(VV,VVolt);
fprintf(fileid,'%d',VV)
figure
plot((-28:-14),VV,'o',VVolt,c,'*');
ylabel('voltage');
xlabel('current');
legend('VV','c');

Output:

Conclusion:

The interpolation model using xlc doc data will be verifyed succesfully
