Warning: Could not start Excel server for import, 'basic' mode will be used. Refer to HELP XLSREAD for more information.
xlsread can only read .xlsx files on MS Windows systems that have Excel installed. On MS Windows systems that do not have Excel installed, and on Mac and Linux systems, xlsread() can only read .csv files.
It is recommended that you use readtable() [R2013b or newer] or readmatrix() [if you have R2019b or newer]
