Difference between x = 0:0.1:2*pi and linspace(0,2*pi,0.1)

i was going through a matlab code and it had x = 0:0.1:2*pi written

i wanted to ask what is the difference between this and linspace and how it is used?

Linspace divides the interval into the exact number specified, while colon notation just keeps increasing the interval by the middle number not to exceed the last number.

x=0:.1:2*pi

x = 1×63

0 0.1000 0.2000 0.3000 0.4000 0.5000 0.6000 0.7000 0.8000 0.9000 1.0000 1.1000 1.2000 1.3000 1.4000 1.5000 1.6000 1.7000 1.8000 1.9000 2.0000 2.1000 2.2000 2.3000 2.4000 2.5000 2.6000 2.7000 2.8000 2.9000

y=linspace(0,2*pi,63)

y = 1×63

0 0.1013 0.2027 0.3040 0.4054 0.5067 0.6081 0.7094 0.8107 0.9121 1.0134 1.1148 1.2161 1.3174 1.4188 1.5201 1.6215 1.7228 1.8242 1.9255 2.0268 2.1282 2.2295 2.3309 2.4322 2.5335 2.6349 2.7362 2.8376 2.9389

See the difference.
