How to plot using semilogy

how would I plot using semilogy()

for

 t=1.57123822236922 1.60940312809172 47.3847818221929 1.55948917911167 1.28901816023201 8.96854743796101 0.966229733431288 0.656941993512154

and the x-axis is length(t);

The documentation on the function provides the information you're looking for.

You can set x = 1:length(t).

would y just be t in this case?

t = [1.57123822236922 1.60940312809172 47.3847818221929 1.55948917911167 1.28901816023201 8.96854743796101 0.966229733431288 0.65694199351215];
semilogy(t)
