Matlab function cheat sheet astra 07 oct. 2019 clear workspace plot responses all variables in workspace all commands in command window for first. Advanced Matlab Commands. Let’s take a look at some of the Advanced commands which are as given below:-1. Whenever you are dealing in control system designs in engineering, the Nyquist plot contours, etc give you a mark of the stability in the system, we can customize the style of the plot in the Matlab (like the color and line type, etc).

fprintf

%4.2f in the formatSpec input specifies that the first value in each line of output is a floating-point number with a field width of four digits, including two digits after the decimal point. %8.3f in the formatSpec input specifies that the second value in each line of output is a floating-point number with a field width of eight digits, including three digits after the decimal point. n is a control character that starts a new line.

Line Properties

Color:
red = r
green = g
blue = b
cyan = c
magenta = m
yellow = y
black = k
white = w

none
LineStyle:
solid line = -
dashed line = --
dotted line = :
dash dotted line = -.
no line = none
Marker:

circle = o
plus sign = +
asterisk = *
point = .

cross = x
square = square or s
diamond = diamond or d
none = none
MarkerEdgeColor & MarkerFaceColor:

same as color
MarkerIndices

max

mean

sum

fprintf

%d in the formatSpec input prints each value in the vector, round(a), as a signed integer.

building arrays/loops

max loop

MATLAB–Python–Julia cheatsheet

Dependencies and Setup¶

In the Python code we assume that you have already run importnumpyasnp

In the Julia, we assume you are using v1.0.2 or later with Compat v1.3.0 or later and have run usingLinearAlgebra,Statistics,Compat
