x=1:733;
y=Ppvproto.PVPower(24:756);
plot(x,y,'.')% % if it doesn’t work upload your excel file which reveals the entire contents

It seems the problem is because the numbers data from excel are written as string array instead of numerical/logical array.

Can I ask how to change it?

Try

str2double() 

if it doesn't work please upload your excel file.
