data = {'abc' , 'def' , 'ghi'}
I have a cell array named data. Now i need to move the contents to another index in the same array and delete the older contents.
for example: data([4 5 6]) = data
This will give the result as data = {'abc' , 'def' , 'ghi', 'abc' , 'def' , 'ghi'}. Instead of this i just need to move the contents based on the index number and empty the contents in the older position.
Answer should be like this,
data = {[],[],[],'abc' , 'def' , 'ghi'}
How can i do it?
Thanks a lot

how if we have a cell that contains binary image or another image. how can we move that image that was stored o a new variable? so that we can show it using imshow().

new_variable = name_of_cell{row_index, column_index};
imshow(new_variable)
but note that imshow() would be happy with
imshow( name_of_cell{row_index, column_index} );

I want to move it in the same cell array. Not by shifting it to another new cell array

If i get the index as [4 7 9] then above does it work. I will get the random index and based on the index number i need the place the contents in the cell array

That case you have to initialize the cells empty with some name...and replace your data with the indices...like get iwant and rename it as data again...
