MATLAB: Difference between commands of CTFT and DTFT

digital image processingdigital signal processinghelpMATLAB

I am bit confused in difference between application of fourier command,is it only applicable to CTFT (continous time fourier transform) or is it also applicable to DTFT(discrete time fourier transform) ?

If I understand your Question correctly, the Symbolic Math Toolbox fourier function computes the analytic Fourier transform of a symbolic expression. I would consider that to be continuous-time. It takes only symbolic arguments, not sampled data.
The fft function computes the Fourier transform of sampled signals.
