Time in seconds ode45

Hi,

How can I create an array of 10 seconds start from 0 second increment by 0.1 seconds to 10 seconds?

Thank you

I tried to use seconds function but it didn't work I need this time for ode45 tspan

Create the ‘tspan’ argument as a vector of more than two elements:

tspan = 0 : 0.1 : 10;

.

But matlab can't understand if 10 is a seconds and this is the issue!

Why is that an issue? What problem / error / etc. are you experiencing when you're using a time span vector like Star Strider showed?

[Shahad Alomani]

no error, tspan is only take t0 and tf which final value, I need to increment it with 0.1 and matlab can't understand that 10 is in seconds. I need the 10 to be in unit of seconds.

[Steven Lord]

The ODE solvers neither know nor care what units the time span vector is in. It could be seconds. It could be nanoseconds. It could be years. It doesn't even need to represent time.

As long as you've written your ODE function so it handles correctly the time value with which the ODE solver calls it you should be okay.
