So I have read an excel file from a set data by using xlsread(), and now I want to get information from the excel file that is 9354x4. And I am trying to get all the data from row 1 to row 365 that is in the fourth column, I have tried using num1(365,4)*Note num1 is the variable that I used to read the excel file*, and it only gives me the data that belongs to row 365 column 4, but what I want is everything starts from row 1 to row 365 that is in column 4, please help.

As suggested by Pawel, use a colon as a subscript. num1(1:365,4) should do the trick. Refer https://www.mathworks.com/help/matlab/ref/colon.html for more information on other indexing expressions.
