- Left hand side: use () to keep it as cells not braces for extraction of the content of cells.
- Right handside: make 0 a 1x1 cell so that it can be stuck into all of the cells on the left via scalar expansion

Hi all,
I am declaring a cell array to hold some numeric and non numeric data. I want to set the first row, all columns, equal to the numeric value zero. Something like this:
myCell = cell(5, 500);
myCell{1,:} = 0;
Which gives the error:
The right hand side of this assignment has too few values to satisfy the left hand side.
I've tried a number of other things, none worked, so have resorted to doing it in a loop. It works, but I really don't like it. Is there a simple way I'm missing?
Cheers, Karl

This is valid also in the case where I have a cell with 10 columns and 71842 rows and I want to fill with the number one only the rows between 2695 and 2746 of column one?

@Flavia something like
myCell(2695:2746, 1) = {1}

This also works:
A =
1 2 3
4 5 6
7 8 9
in order to zero the ith row: (i = 1)
A(1,:) = [0]
>> A =
0 0 0
4 5 6
7 8 9

Nice! Thanks (Had the same issue) Never thought about using the curly brackets around the zero.
