MATLAB: How to calculate the cell arrays length

cell arraysMATLAB

Hi, I have this kind of cell array. As you can see in row 16, from the 7th column all the value are equal to []. it means that this row has a different lenght than the others, that are longer. Do you know how to calculate the length of the rows? And how to access to the first number of the cells (for instance in [0,1,1] I would get 0)? Thanks in advance!

This calculates the number of elements in each row

n = sum(~cellfun(@isempty, Obs_Val), 2)

You can calculate first element of a cell like this

Obs_Val{2, 4}(1) % cell in 2nd row, 4th column

MATLAB: String Length

Your input variable is a cell array. Each string is an element in that cell array and so length reports 2, because you have 2 elements. If you do length(string(1)) then you still try to access the cell element itself rather than its content. However, if you do length(string{1}) then this should actually report the length of the first string, because using curly bracket you can access the content of a cell. If you search the documentation for "cell array" you will find more details on this.

MATLAB: Message length

Hi Vino,

if you do

edit msgbox

you will see at line 274 (at least in R2012a I'm looking at) a call to textwrap with argument 75. So: msgbox will make the box as large as to fit the string you entered, but if it will be too long, it will be broken such that it is 75 characters at most. Of course you could call textwarp yourself before calling msgbox if you want to have less characters in a row.
