Project - Data Handling and Interpolation

First we create an excel filevi.xlsx with voltage and current values.

Then import that data to matlab.

Then read that excel sheet (T=xlsread('vi.xlsx')

Then interpolation done by using interpn.

Perform the interpolation in the range of -17.3:0.1:0.9.

The blue circle represents the samples and the line represents the cubic interpolation.

Here v is the voltage values and i is the current values.

Where xq is the interpolation range.

Interpolation is a technique for adding new data points within a range of a set of known data points.

By using the data cursor we can find out the corresponding current values of given voltages.
