function that returns the first element in a cell in matlab

To return the first element in a cell in MATLAB, you can use the curly braces { } to access the contents of the cell. Here's an example function that takes in a cell array and returns its first element:

main.m
function firstItem = getFirstItem(cellArray)
   firstItem = cellArray{1};
end

This function uses the curly braces to access the first element of the cellArray and assigns it to the variable firstItem.

You can call this function with any cell array as an argument, like this:

main.m
>> myCellArray = {'apple', 'banana', 'cherry'};
>> first = getFirstItem(myCellArray)
first =
apple
