Project - Data Handling and Interpolation

Initially the data is read from the excel sheet named 'VI' using xlsread function, then the two coloumns are taken as input such as Voltage(v) & Current(i). Then using the interp function the range i.e Voltage values (v1){ -17.3 to 0.9} with 0.1 interactions is used to plot various values of current'i1'. After that the original values and the new generated values are been plotted using plot function with various patterns.Later on as requested various voltage values 'v2' are again called and similiarly using the interp function the current values are generated as 'i2'. Then the graph is represented using grid lines,xlabel and ylabel. Similarly the title and legend are also included to showcase more data and productive information in the graph. Later on fileid & fprintf function is used to save all the data of v2 and i2 in serial order using for loop and then the file is saved as Interp_table.txt. All the files such as excel sheet , Interp_function.m , Interp_graph for figure & interp_table for text file are attached for references.
