pseduo decimal randeom number

can anyone have MATLAB code for pseduo decimal random number generator. pseduo decimal random number generator is initiated with some seed value which also has decimal number. It is iterative mathematical equcation.

Don't know what you mean by pseudo decimal random number generator. What doesn't the rand( ) or randi( ) function do that you want? Can you give an example of the types of outputs you would expect?

[Scott MacKenzie]

Computer algorithms to generate random numbers are pseudo random. The seed you mention is built in to MATLAB's random number functions. So, again, it's not entirely clear what you are after.

If you want random decimal integers, use randi. For example, to generate 10 random integers in the range 1 to 5:

>> x = randi(5,1,10)
x =
     1     5     2     2     3     3     5     5     3     5

Exactly what does rand do that does not satisfy you? Why do you think it is inadequate for your needs? You should consider that numbers in MATLAB, as double precision numbers are NOT decimal numbers anyway, since they are stored in binary form. The thing is, this is true for virtually all programming languages. So what would it gain you if you had some truly "decimal" random number generator?

pseduo decimal random number genartor means that generate the decimal random number by given seed value that is also in decimal form. for example: seed value is : 2.5564 and after applying this seed value and total count of random numbers in that equcation, i can obtain the decimal random numbers. whenever, i applied same seed value in that equcation in future, same sequence of numbers are generated.

Hi sudir,

rand(1,8)
disp('reset')
