Trying to generate a plot from an Excel file.

Hello all! I am trying to take some imported data from an excel file (.xls) in order to generate a plot of it where the x-axis is the A column and the y-axis is B-column.

Here is the code:

filename = 'PlotCycles.xls';

sheet = 1;

xlRange = 'A1:A1430';

ylRange = 'B1:B1430';

x = xlsread(filename, sheet, xlRange);

y = xlsread(filename, sheet, ylRange);

Plot(x,y)

I am getting an error that says "Warning: Could not start Excel server for import, 'basic' mode will be used. Refer to HELP XLSREAD for". This is fine I think because I only want a numerical array anyways. The next error I get is:

"In xlsread at 187

In PlotCycles at 5

Warning: Range cannot be used in 'basic' mode. The entire sheet will be loaded.

In xlsread at 200

In PlotCycles at 5

Error using xlsread (line 247)

File contains unexpected record length. Try saving as Excel 98.

Error in PlotCycles (line 5) x = xlsread(filename, sheet, xlRange);"

I'm really not sure what to do in this situation, I'd appreciate any input thanks!
