Hello how are you? How can I create a column vector with specific values, that is, the first value would have to be 0, the second would have to be 63 up to 1, the vector would have to be as follows.
vec= [0
63
62
.
.
2
1]
any help is helpful.

vec = [0; (63:-1:1).']
vec = 64×1
0 63 62 61 60 59 58 57 56 55

You can use the colon operator provided by MATLAB to create a vector with specified increment/decrement.
Writing
vec = 63:-1:1
vec = 1×63
63 62 61 60 59 58 57 56 55 54 53 52 51 50 49 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34
will create a row vector of 63 consecutive values starting from 63 and going all the way down till 1.
But you need to transpose it so as to convert it into a column vector.
vec = (63:-1:1).'
vec = 63×1
63 62 61 60 59 58 57 56 55 54
Finally,
vec = [0; (63:-1:1).']
vec = 64×1
0 63 62 61 60 59 58 57 56 55
will return you a column vector with the first element as 0 and the next 63 consecutive numbers.
