F prime and F star

That is how I would read them.

My take on it from the USA.
Peer comment(s):

agree Margaret Schroeder : Verified by a mathematician. This is the correct reading.

agree Attila Piróth : That's it. IN UK F* is also read as F asterisk.

derivative, transpose

F' is the derivative of a function:

F* as far as I know is not used for a function, but can be used for a matrix, this is the transposed matrix:

Special notations apply for Matlab:

F-prime and F-star

The meaning may be different depending on the discipline, but when reading a formula or equation n English, the notation is normally pronounced as F-prime and F-star.

Didlier's explanation is from calculus and matrix algebra respectively.

F* also is typically used for the "closure of F".

F' is frequently used for "a variation of F", e.g. "given the set F, find F' such that L(F') = G(F), where L and G are given functions".

Hope this helps,
