Check the size of the variable num.
whos num
It seems, num is only a array with once column.

num = readmatrix('viveek.xlsx');
x = num(:,1);
y = num(:,2);
x1 = -17:0.09:0.9;
y1 = interp1(x,y,x1,'spline');
figure(1);
plot(x,y,'+b',x1,y1,':.');
title('linear interpolation');
fig = gcf;
axObjs = fig.Children;
dataObjs = axObjs.Children;
x = dataObjs(1).XData;
y = dataObjs(1).YData;

The variable num is empty, as it shows in its size. You can't access any elements from it.
Check if the excel file is empty or not. What are the contents of the excel file?

Well, yes, of course you should use an Excel file with values.
