1234.5 instead of 1.2345e+03

When I read a variable from Excel with value say, 1234.5, Matlab reads in as 1.2345e+03. Instead I want the original format to be preserved (ie., it should stay as it is say, 1234.5 in this example). I have tried "format short g" etc, but these deal with number of digits after the decimal. How can I set the correct format? Thanks, Ganesh

Internally 1234.5 and 1.2345e+03 are the same numbers. The different notation concerns only the output to the command windows. Therefore it is necessary that you post more relevant details of your problem.

It depends on the context of where you want this number displayed, but here is one way to show this number the way you want:
x = 1234.5;
sprintf('%5.1f',x)

In MATLAB-speak, the "format" generally refers to how the variables are displayed, not to how they are stored internally, or used for computation.
Can you confirm that your variable xdata and ydata are being imported as numeric arrays, and not as text? That could be the problem. Are you able to post a small snippet of self-contained code that exhibits the problem?

What evidence do you see that the fitcurvedemo call is not working?
Does the issue only affect the xdata, or only affect the ydata ? For example if you were to divide the ydata by 10 so that it remained less than 1000, does that work?
