What Is A Seed In Matlab

Simple but effective example of region growing from a single seed point.

What is a seed in matlab.

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. Setting seed in random normal. Region growing stops when a significant difference between the seed and the neighbour pixel is found. In 2 rand k is producing a kxk matrix of uniform random numbers then producing a 1x5 vector of uniform random numbers.

But what if you want to repeat that random number for the purpose of duplicate your simulation results. The algorithm for region growing scans seed image s x y to find a seed. For example the following code sets the seed to 1 and the generator to mersenne twister. Set the seed and generator type together when you want to.

Learn more about seed random matlab. Every time you use rand it gives you a random number that is what rand is for. The region is iteratively grown by comparing all unallocated neighbouring pixels t. To create one or more independent streams separate from the global stream see randstream.

The rng function controls the global stream which determines how the rand randi randn and randperm functions produce a sequence of random numbers. Seeding the random number generator means initializing it to a certain status. Seeding inside the loop means that all random numbers created inside the loop will be the same in each iteration. The rng function controls the global stream which determines how the rand randi randn and randperm functions produce a sequence of random numbers.

Ensure that the behavior of code you wrote in a. 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. So i m not sure what the point of 2 is. To create one or more independent streams separate from the global stream see randstream.
