A cell is like a bucket. You can throw anything you want into the bucket: a string, an integer, a double, an array, a structure, even another cell array. Now let’s say you have an array of buckets – an array of cells or a “Cell Array”. Another way to use the cell is to refer to the cell itself, rather than the contents of it, and for that you use parentheses. The item it refers to must be a cell.

This set of code is entirely equivalent to the first set of code. 1, replacing any bucket that was already there. You can use either way and I don’t really think one way or the other is really preferred. You can use whatever way is easier for you to think about it.
Maybe one way will be more intuitive for you than the other way, but again, they are equivalent. Initialize a cell array with three different types of contents. If you get strange error messages while working with cells or cell arrays, one easy thing to try is to change your braces into parentheses, or your parentheses into braces, and see if that eliminates the errors. It’s also possible to mix indexing of the row and column of the cell array with the indexing of the contents of the single cell at that row and column of the cell array. For example, let’s create a cell array of 2 rows and 3 columns, and in every cell of that let’s put a 4 element integer array. Then we’ll access the second element of the integer array at the cell in row 1, column 2 of the cell array.
Create an empty cell array of 2 rows and 3 columns. Each element in the array is a single cell. An alternate way of specifying is given on the next line. Does MATLAB only calculate to 4 significant digits?
Don’t worry – your number is not truncated. It uses full double-precision floating point numbers to calculate everything. However, by default it only prints a few decimal places to the screen in the command window. Why does the transpose operator take the complex conjugate? The bare apostrophe is an operator that takes the complex conjugate transpose.
