i want to generate a sequence of n numbers

How would i generate a secuence of N amount of numbers starting at -4 and going up in steps of 2?

Cheers

Have a look here: Generating a Numeric Sequence

Kind regards,

Those sequence codes work if i have an end value of the secuence but i need the sequence to contain n amount of elements regardless of the last value

Those sequences work with variables as end values as demonstrated in the answer by Benni.

Answer 1

You can create sequences with the colon operator (:), for exapmle

v = [4:2:100];

creates v = [4, 6, 8, ... , 100] with values starting at 4, an increment of 2 and stop value 100.

For N numbers starting at -4 and an increment of 2, you have to calculate the stop value:

N = 10;

start_val = -4;
inc = 2;
stop_val = (N-1)*inc + start_val;

v = [start_val:inc:stop_val];

Answer 2

[Voss]

start = -4;
increment = 2;
N = 8;

sequence = start + (0:N-1)*increment;
