Hi KR,
You can consider using “dictionary” instead of matrix since you are mapping cost to each part number. Dictionary is a datatype which allows us to lookup data mapped to a key. Since you want to lookup costs for a given part number, part numbers should be the “key”. Consider following the below link for more information on using the “dictionary” datatype in MATLAB.
Also, the use of “menu” is not recommended by the MATLAB documentation. You should consider using “listdlg” instead of “menu” method. “listdlg” creates a list-selection dialog box just like the “menu” method. You can use the below code for reference:
partNumbers = [1741 2377 3203 3571];
partCosts = [0.37 0.21 0.31 0.17];
prodDict = dictionary(partNumbers, partCosts);
PN=listdlg('PromptString','Select a part number','SelectionMode',...
'single','ListString',string(partNumbers));
Q=input('Enter quantity of the selected part: ');
cost = prodDict(partNumbers(PN)) * Q;
fprintf('Cost of the part is %f\n', cost);
You can find more information about “listdlg” in MATLAB documentation by following the below link:
