MATLAB: How to…column vector

columncolumn vectorvector

Create an evenly spaced column vector of values from 2.2 to 5.3 in increments of 0.1.

x = j:k creates a unit-spaced vector x with elements [j,j+1,j+2,...,j+m] ...

x = j:i:k creates a regularly-spaced vector x using i as the increment ...

Thus the default value of the step, i, is +1 (one).

>> vec = -1:+1:-5 
vec =
  1×0 empty double row vector

and

>> vec = -1:+5
vec =
    -1     0     1     2     3     4     5
