Does the discrete cosine transform (dct command) in MatLab use the FFT algorithm?

Hi, I am using the Chebyshev transform and want to utilize and want to use the efficiency of FFT algorithm. But the Chebyshev transform is actually a cosine transform. So should I use "dct" command directly or use the "fft" command in order to do a fast transform as FFT? Is the FFT algorithm included in the MatLab "dct" command? Thanks in advance for any help!
