Hello Berk,
you can use 'c2d' function in matlab to convert a continous transfer function into a discrete transfer function. eg Hc=h=tf([1,0],[1, 0.9425])
Hc=h=tf([1,0],[1, 0.9425])
Hd=c2d(Hc,Ts)
here Ts is the sampling time.

right, my result was same as @Oncel AKIN's. I guess that there is a mistake too.
i really want to get clear answer about this question as soon as possible!

c2d() offers a variety of methods to convert from continuous to discrete. One of those methods will match your expected result.

How can I write a program in Matlab which determines the characteristics of the analogue filter which include the following:
• The step response of the RC low pass filter
• The impulse response of the RC low pass filter
• The frequency response of the RC low pass filter
