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().

Walter Roberson 2019-1-10

在 MATLAB Online 中打开

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

KSSV 2016-9-2

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...
