Array indices must be positive integers or logical values
2 views (last 30 days)
I'm relatively new to MATLAB, and I'm trying to get my code to read some Excel files, but one row has negative integers. Is there any possible way to get the code to read the files properly? I'm trying to plot the results and it should look like a sine wave crossing over the x-axis, so there should be negative values... I've attached the Excel file and a screenshot of the segment of code where the error occurs.

I tried the same code letter for letter and I was able to make it work. Are you on the Windows OS?
Also, since you're using R2018b, try using readmatrix or readtable instead. They're both preferred over xlsread.
