@shamsa khalid

I'll give a general idea. You need to search some functions on the help documentation.

The chart is essentially a table. Perhaps you can create a table and then write a function to do the following:

Request user input for the 4-band color code. (See https://www.mathworks.com/help/matlab/ref/input.html)
identity the 4-band color code in the standard RGB
lookup the corresponding values from the table
determine the resistance of the resistor.
display the result (see https://www.mathworks.com/help/matlab/ref/fprintf.html)

在 MATLAB Online 中打开

prompt = "Enter band 1 ";
a = input(prompt)
prompt = "Enter band 2 ";
b = input(prompt)
prompt = "Enter band 3 ";
c = input(prompt)
prompt = "Enter band 4 ";
d = input(prompt)

After giving some thoughts, I think RGB values and the table are not needed in your case. If the color band is Brown, Orange, Green, Gold, then you can display an image and ask the user to enter accordingly:

code = [1 3 5 G]

and hit 'Enter'. The algorithm should determine and display the resistance as:

Ohm with

% tolerance.

Note that Band #3 Black should be 0 because
