limit rows and columns readcell in matlab

To limit the number of rows and columns that are read using the readcell function in Matlab, you can use the optional Range parameter. This parameter specifies the range of cells to read, in the format A1:C3 (reads cells A1 through C3).

To limit the number of rows and columns, you can adjust the range accordingly. For example, to read the first 5 rows and first 3 columns of a cell array dataTable, you can use the following code:

main.m
dataTable = readcell('myExcelFile.xlsx', 'Range', 'A1:C5');
60 chars
2 lines

This reads cells A1 through C5, limiting the data to the first 5 rows and first 3 columns. You can adjust the range as needed to limit the number of rows and columns.

If you want to read all rows up to a certain row number and all columns up to a certain column number, you can use the : to specify all cells up to the specified row or column. For example, to read all rows up to the 10th row and all columns up to the 5th column, you can use the following code:

main.m
dataTable = readcell('myExcelFile.xlsx', 'Range', 'A1:E10');
61 chars
2 lines

This reads cells A1 through E10, limiting the data to the first 10 rows and first 5 columns.
