The table we created above has only 6 elements in it and suppose we need a more detailed table. In order to do that, instead of a single new x value, we can define an array of new x values, the interp1 function returns an array of new y values:
new_x = 0:0.2:5; new_y = interp1(x,y,new_x);
Let’s display this table
[new_x',new_y']
The result is
ans =
0 0
0.2000 4.0000
0.4000 8.0000
0.6000 12.0000
