What does this Matlab statement means? t=0:1/100:1 and ...

say you have
t=0:1/100:1 and j=0:1/100/10
First what does these statements mean? what will be the difference?
Thank you

This t=0:1/100:1 can be rewritten (for clarity) as this

t = 0 : 1/100 : 1

it says: t will go from 0 to 1 in steps of 1/100

- - - -

j=0:1/100/10

Can be rewritten as

j = 0 : 1/100/10

maybe it's not written correctly. Maybe you meant j = 0 : 1/100 : 10

in this case it means: j will go from 0 to 10 in steps of 1/100
