Matlab class array / other array

[K41]

Okay so what does this line of code mean:

snleg = strtrim(cellstr(num2str(alf_deg.')));

I did some research and it is ultimately removing whitespace (comma's, spaces etc) from a file scanned in, but I don't understand the argument of the function.

I don't understand what cellstr is or num2str. I read that it might be to do with cell arrays and they can't or can be modified? I am very confused :sI imagine num2str converts a number to a string value but why do we need to do this?

Please note, alf_deg was a variable already initialized in the code. Why do we need a .' in here?

.' returns the transpose of the matrix alf_deg.

num2str does what it says - converts a number to string.

cellstr is used to convert string/character arrays to cell arrays.

strtrim removes leading and trailing white spaces.
