Final answer:
To combine two transfer functions in a row, you can use the 'series_f()' function or the 'f_combine()' command.
Step-by-step explanation:
To combine two transfer functions in a row, you can use the 'series_f()' function. This function multiplies the two transfer functions together, representing the effect of one transfer function followed by the other. Here is an example:
G1 = f([1], [1, 2])
G2 = f([3], [1, 4])
G_combined = series_f(G1, G2)
Another option is to use the 'f_combine()' command, which also performs series combination of transfer functions. Here is an example:
G1 = f([1], [1, 2])
G2 = f([3], [1, 4])
G_combined = f_combine(G1, G2)
