hi everyone, i'm using readtable function to get data from excel in this way:
matrix = readtable('sala_prove.xls');
now i have to select a specified row, for example
row = matrix(4,:);
at this point i should to select again a specified value, for example the first one of the row that i have just selected:
row(1)
but it doesn't work. there's an error message "You can not subscript a table using only one subscript. Table subscripting requires both row and variable subscripts." what does it mean? how can i resolve to select the first (or anyother) value in the row?

row = matrix(4,:); selects a single row, but the result is still a table. You can use
row = matrix{4,:};
to extract the values.
