Want to create a time vector

Hello guys,

i got stuck in this one. I want to create a time vector like -10 <= t < 10 ( because using <= then i have to include -10 in t and not include 10 in t.)

i did something like:

t = -10:0.01:10;

stp = @(t) double(t>=0);

Is my code right?

I have no idea what you want to do, although the linspace function may be a more precise approach —

t = -10:0.01:10-0.01                       % 'colon'

t = 1×2000

-10.0000 -9.9900 -9.9800 -9.9700 -9.9600 -9.9500 -9.9400 -9.9300 -9.9200 -9.9100 -9.9000 -9.8900 -9.8800 -9.8700 -9.8600 -9.8500 -9.8400 -9.8300 -9.8200 -9.8100 -9.8000 -9.7900 -9.7800 -9.7700 -9.7600 -9.7500 -9.7400 -9.7300 -9.7200 -9.7100

t(end)

ans = 9.9900

t = linspace(-10, 9.99, 2000)               % 'linspace'

t = 1×2000

-10.0000 -9.9900 -9.9800 -9.9700 -9.9600 -9.9500 -9.9400 -9.9300 -9.9200 -9.9100 -9.9000 -9.8900 -9.8800 -9.8700 -9.8600 -9.8500 -9.8400 -9.8300 -9.8200 -9.8100 -9.8000 -9.7900 -9.7800 -9.7700 -9.7600 -9.7500 -9.7400 -9.7300 -9.7200 -9.7100

t(end)

ans = 9.9900
