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

在 MATLAB Online 中打开

myCell(1,:) = {0}

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

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?
