Project - Data Handling and Interpolation

Voltege and current data Of labrotory From given excel File and anathe given 15 Volegae values are given in the Que.

VvsI=xlsread('C:\Users\AAKASH KULTHE\Downloads\VI.xlsx');

% Read the of Voltage and current from given excel File.

V=VvsI(:,1);

% Load the given Voltage Value of row 1.

I=VvsI(:,2);

%Load the Given Current Value of Row 2.

Range=-17.3:0.1:0.9;

% define the Range of voltage Between -17.3 to 0.9 with 0.1 Interval.

P1=interp1(V,I,Range,'linear');

%interpolation to the missing Value Betweem the range.

subplot(211);plot(Range,P1);

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];

% Another 15 Given Voltage Values.

P2=interp1(V,I,VV,'linear');

%interpolation To the missing or depending variable of Given 15 v Values.

subplot(212);plot(VV,P2);

title('15 voltage values are given in the question');

% Create the The text file To stored the VI values.

fprintf(fileid,'%d %f\n',Range);

% Stored the VI data in text File.
