How to create a 1400 × 2 matrix of normally distributed random multiples of 10?

I'm trying to create a 1400 × 2 matrix of normally distributed random multiples of 10 (i.e. 200, 210,

220, etc.) with a mean of 500 and a standard deviation of 100, using randn, round , and

other operations. So far I have:

mu = 500;

stdev = 100;

s = round([(randn(1400,2) * stdev) + mu])

..but I have trouble with the "multiples of 10".. how do I implement the command to only display random (!!) multiples of 10? Thank you.

I can multiply by 10

s = round([(randn(1400,2) * stdev) + mu]) * 10

but is that what is asked here?

[Matt J]

What is asked makes no sense. "Normally distributed" implicitly means that s can take on any value.

I know, right... that through me off as well

You can round(x, -1) to round to the nearest multiple of 10.

However, Normal Distribution is inherently a continuous distribution, and it is contradictory to have "normally distributed" quantized values (other than quantized due to the limits of precision of the calculation method)
