Don't name a variable step and degree because there are inbuilt MATLAB functions.
help step
STEP Step response of dynamic systems.
[Y,T] = STEP(SYS) computes the step response Y of the dynamic system SYS.
The time vector T is expressed in the time units of SYS and the time
step and final time are chosen automatically. For multi-input systems,
independent step commands are applied to each input channel. If SYS has
NY outputs and NU inputs, Y is an array of size [LENGTH(T) NY NU] where
Y(:,:,j) contains the step response of the j-th input channel.
For state-space models,
[Y,T,X] = STEP(SYS)
also returns the state trajectory X, an array of size [LENGTH(T) NX NU]
for a system with NX states and NU inputs.
For identified models (see IDMODEL),
[Y,T,X,YSD] = STEP(SYS)
also computes the standard deviation YSD of the response Y (YSD is empty
if SYS does not contain parameter covariance information).
[Y,...] = STEP(SYS,TFINAL) simulates the step response from t=0 to the
final time t=TFINAL (expressed in the time units of SYS). For discrete-
time models with unspecified sample time, TFINAL is interpreted as
the number of sampling periods.
[Y,...] = STEP(SYS,T) specifies the time vector T for simulation (in
the time units of SYS). For discrete-time models, T should be of the
form 0:Ts:Tf where Ts is the sample time. For continuous-time models,
T should be of the form 0:dt:Tf where dt is the sampling period for the
discrete approximation of SYS.
[Y,...] = STEP(SYS,...,OPTIONS) specifies additional options such as the
step amplitude or input offset. Use stepDataOptions to create the option
set OPTIONS.
When called without output arguments, STEP(SYS,...) plots the step
response of SYS and is equivalent to STEPPLOT(SYS,...). See STEPPLOT
for additional graphical options for step response plots.

help degree
--- help for graph/degree ---
DEGREE Degree of nodes in a graph
D = DEGREE(G) returns the degree of each node of G, in a column vector.
D = DEGREE(G, NODEIDS) returns the degree of the nodes specified by
NODEIDS. NODEIDS can be a numeric array of node IDs or an array of
node names. D has the same dimensions as NODEIDS.
Example:
% Create a graph, and then compute the degree of its nodes.
s = [1 1 1 4 4 6 6 6];
t = [2 3 4 5 6 7 8 9];
G = graph(s,t);
d = degree(G)
Example:
% Create a graph, and then compute the degree of a subset of nodes.
s = {'a' 'a' 'a' 'd' 'd' 'f' 'f' 'f'};
t = {'b' 'c' 'd' 'e' 'f' 'g' 'h' 'i'};
G = graph(s,t)
nodeIDs = {'a' 'c' 'e'}';
d = degree(G,nodeIDs)
