Hi I need to implement this function using matlab, where x and t are variables.

Please tell me how to do this.

Hi Kintali Narendra

this is John BG <mailto:jgb2012@sky.com jgb2012@sky.com>

I was just highlighting the point that certain constraints should be applied to f(t) before attempting the definition of D, otherwise it might happen that the integral cannot be solved, integral for instance Inf, and then D couldn't be defined.

Thanks for letting us know that you have already found the solution.

I hope you don't mind me asking the following

Are Mr Chunmei Chi and Mr Feng Gao provide some sort of script, to help you up to speed? or do you have to write the script on your own?

How are you going to connect this

to the expression shown in your question?

there's still a pole 1/(x-t) right on the edge of the integration interval.

Precisely to develop the fractional derivatives, Mr Chi and Mr Gao assume f(x) to have the following shape

this particular constraint on f(x) allows the application of the Fourier transform to carry on.

Do you need further assistance for this question?

If not, would you consider telling David to copy past the link as answer, and then you would consider clicking on the Accept Answer for the supplied link containing the solution?
