Understanding Lab Results: data
Sweep DC bias and AC frequency: V out is a function of V_bias and freq: V out [V_bias,freq]
? V out returns all data, for all index values 0 through N of each sweep
? V out[0,1] returns V_bias only at index 0, and freq only at index 1
? V out[::,1] returns all values of V_bias, and freq at index 1
? V out[0,::] returns V_bias at index 0, and all values of freq
? V out[0::2::6,::] returns V_bias at index values 0, 2, 4, 6 and all values of freq
SYNTAX NOTE: Double colon :: is equivalent to “all values” like a wildcard.
For example[a::b::c] a=start, b=increment, c=stop.

Concept: data in dataset is a function of one or more variables, and all data is indexed beginning with index value 0.
Index
for freq:
0 1 2 3 4
5 6
Index for
V_bias = 0
if 2V is the
first value.
