Step Function
A signal that switches from zero to one at a specific time.
u = [zeroes(1, N), ones(1, N)]
Discrete-Time Unit Step (MATLAB)
Discrete-Time Impulse
A signal that is zero everywhere except at one time index.
delta = [zeroes(1, N), 1, zeroes(1, N)]
Discrete-Time Unit Impulse (MATLAB)
Ramp Signal
A signal that increases linearly with time.
ramp = 0:1:N
Ramp Signal (MATLAB)
Rectangular Pulse
A finite-duration signal formed by subtracting two step functions.
M-File
A file containing MATLAB commands saved for reuse.
Script File
An M-file that runs commands sequentially without input/output arguments.
Function File
An M-file that accepts inputs and returns outputs.
Function Definition
The first line of a function M-file defining its name and arguments.
size Function
Returns the dimensions of a matrix or vector.
find Function
Returns indices of elements that satisfy a logical condition.
