What Is A Seed In Matlab

For example the following code sets the seed to 1 and the generator to mersenne twister.

What is a seed in matlab. In 2 rand k is producing a kxk matrix of uniform random numbers then producing a 1x5 vector of uniform random numbers. Seeding the random number generator means initializing it to a certain status. Every time you use rand it gives you a random number that is what rand is for. So i m not sure what the point of 2 is.

Simulink is the integrated environment of system modelling and simulation which is being widespread used this paper describes the matlab visual simulation of the propagation path loss model for. Region growing stops when a significant difference between the seed and the neighbour pixel is found. When a seed is found the region growing is performed from this point over the originalimage jpg f x y. To create one or more independent streams separate from the global stream see randstream.

Rng seed specifies the seed for the matlab random number generator for example rng 1 initializes the mersenne twister generator using a seed of 1. The region is iteratively grown by comparing all unallocated neighbouring pixels t. But what if you want to repeat that random number for the purpose of duplicate your simulation results. Simple but effective example of region growing from a single seed point.

Setting seed in random normal. Rng seed specifies the seed for the matlab random number generator for example rng 1 initializes the mersenne twister generator using a seed of 1. The rng function controls the global stream which determines how the rand randi randn and randperm functions produce a sequence of random numbers. To create one or more independent streams separate from the global stream see randstream.

Ensure that the behavior of code you wrote in a. Set the seed and generator type together when you want to. Ensure that the behavior of code you write today returns the same results when you run that code in a future matlab release. Learn more about seed random matlab.
