How do I find the value of the cell from a particular row number

I have a data array consisting of 1 row and 4000 columns of data values, I want to find out the value which exists in certain cells, say for example row 1, column 2000, how would i go about this?

"I have a data array ... I want to find out the value which exists in certain cells..."

What do you mean by a "data array": is this a file of some kind, or is it already in the MATLAB workspace?

You can use

[row,col] = find(__);

Answer 1

myArray{ 1, 2000 }

if it is a cell array or

myArray( 1, 2000 )

if it is a numeric array.

Although when using a 1d array I tend to omit the 1 and just use

myArray( 2000 )

which works equally, but

myArray( row, col )

is the generic acess.

That's great cheers, is there a way to do this for multiple cells rather than write out the code again and again. For example if i wanted the data from columns 1000, 2000, 3000 and 4000?

[Adam]

myArray( 1, [1000 2000 3000 4000] )

List your columns in brackets:

extractedColumns = fullData(:, [1000, 2000, 3000, 4000]);

That will give you an array with all the rows and only those 4 columns.
