matlab randint,Matlab的randint函数用法「建议收藏」

大家好，又见面了，我是你们的朋友全栈君。

RANDINT Generate matrix of uniformly distributed random integers.

OUT = RANDINT generates a “0” or “1” with equal probability.

OUT = RANDINT(M) generates an M-by-M matrix of random binary numbers.

“0” and “1” occur with equal probability.

OUT = RANDINT(M,N) generates an M-by-N matrix of random binary numbers.

“0” and “1” occur with equal probability.

OUT = RANDINT(M,N,IRANGE) generates an M-by-N matrix of random integers.

IRANGE can be either a scalar or a two-element vector:

Scalar : If IRANGE is a positive integer, then the output integer

range is [0, IRANGE-1]. If IRANGE is a negative integer,

then the output integer range is [IRANGE+1, 0].

Vector : If IRANGE is a two-element vector, then the output

integer range is [IRANGE(1), IRANGE(2)].

OUT = RANDINT(M,N,IRANGE,STATE) causes RAND to use the generator

determined by the ‘state’ method, and initializes the state of that

generator using the value of STATE.

Examples:

out = randint(2,3) out = randint(2,3,4)

out = out =

0 0 1 1 0 3

1 0 1 2 3 1

out = randint(2,3,-4) out = randint(2,3,[-2 2])

out = out =

-3 -1 -2 -1 0 -2

-2 0 0 1 2 1
