What is step function and ramp function?
The Laplace transform of the unit step function is. (b) Unit ramp function: If the unit step function is integrated with respect to time t, then the unit ramp function results. It is symbolized by r(t). A unit ramp function increases linearly with time. A unit ramp functions may be defined mathematically as.
How to use ramp function in Matlab?
Description. ramp( x ) creates a ramp signal wave with a slope of 1 and returns the value of the ramp at time x . To specify when to generate a ramp signal within a test step, use this operator with the elapsed time ( et ) operator. ramp(et) returns the elapsed time of the test step and is the same as et .
