Ran in:
Since the request has now morphed to do so without using poissrnd, that makes it very likely homework.
In that case, you might want to do some reading. For example, here:
https://www.johndcook.com/blog/2010/06/14/generating-poisson-random-values/
If not, then you need to explain why you cannot use the idea shown there, or why you cannot use poissrnd.
help poissrnd
POISSRND Random arrays from the Poisson distribution. R = POISSRND(LAMBDA) returns an array of random numbers chosen from the Poisson distribution with parameter LAMBDA. The size of R is the size of LAMBDA. R = POISSRND(LAMBDA,M,N,...) or R = POISSRND(LAMBDA,[M,N,...]) returns an M-by-N-by-... array. See also POISSCDF, POISSINV, POISSPDF, POISSTAT, RANDOM.

Check out

assuming that lamda*t in the question is the same as lamda in that function.
