在 MATLAB Online 中打开

Use randn to generate the sequences and modify it accordingly -

avg = 817e-9;
sd = 10e-9;
N = 50;
seq = avg + sd*randn(1, N)
seq = 1x50
1.0e-06 *

    0.8245    0.7998    0.8200    0.8049    0.8297    0.8339    0.7922    0.8071    0.8122    0.8261    0.8032    0.8064    0.8150    0.8077    0.7972    0.8003    0.8210    0.8219    0.8206    0.8213    0.8189    0.8115    0.8254    0.8195    0.8034    0.8113    0.8140    0.8268    0.8225    0.8444

I am not sure about the probability, so I asked MATLAB AI Chat Playground about that and it provided the following -

seq(rand(1,N)>0.25) = 0
seq = 1x50
1.0e-06 *

    0.8245         0         0         0    0.8297         0         0         0    0.8122         0         0         0         0         0         0    0.8003         0    0.8219         0    0.8213         0         0         0    0.8195         0         0    0.8140         0         0         0
