error using xlsread command in matlab

I have written in my matlab program:

EnergyfromSun = xlsread('C:\Homa\Thesis\Matlab\SC\ASTMG173num.xls'); but I got this message:

??? No appropriate method, property, or field UsedRange for class Interface.Microsoft_Excel_14.0_Object_Library._Chart.

Error in ==> xlsread at 302 DataRange = Excel.ActiveSheet.UsedRange;

Error in ==> T2011 at 10 EnergyfromSun = xlsread('C:\Homa\Thesis\Matlab\SC\ASTMG173num.xls');

Try this.

EnergyfromSun = xlsread('C:\Homa\Thesis\Matlab\SC\ASTMG173num.xlsx');

or

EnergyfromSun = xlsread('C:/Homa/Thesis/Matlab/SC/ASTMG173num.xls');

@Lalit: I do not assume, that the filename is wrong. Using the backslash is valid under Windows.

Is there a chart in the .xls file? Is there anything other than plain data?

@ Walter yes there is a chart!! Thanks a lot

The error message is complaining that UsedRange does not apply to charts. I do not know enough about Excel to know what the solution is, other than to delete the chart. Possibly if you specify the range of rows/columns that might solve the problem.
