how to add a column of zeros to a table in matlab

You can use the addvars function to add a column of zeros to a table.

Assuming you have a table called myTable, you can add a column of zeros using the following code:

main.m
myTable = addvars(myTable, zeros(height(myTable), 1), 'NewVariableNames', 'NewColumn');
88 chars
2 lines

This creates a new variable called NewColumn in myTable, and sets all of its values to 0. The zeros function is used to create a column of zeros with the same number of rows as myTable. The height function is used to get the number of rows in myTable.

Note that the 'NewVariableNames' parameter is optional, and can be used to specify a different name for the new column.
