from a python code to matlab code
显示 更早的评论
how can I convert the following code to matlab code?
cuts_under_30 = [hairstyles[i] for i in range(len(hairstyles)) if new_prices[i] < 30]
print("Cuts under 30: " "{}".format(cuts_under_30))

Try this:
clc; % Clear the command window.
close all; % Close all figures (except those of imtool.)
clear; % Erase all existing variables. Or clearvars if you want.
%workspace; % Make sure the workspace panel is showing.
format short g;
format compact;
fontSize = 20;
hairstyles = {'bouffant', 'pixie', 'dreadlocks', 'crew', 'bowl', 'bob', 'mohawk', 'flattop'};
prices = [30, 25, 40, 20, 20, 35, 50, 35];
last_week = [2, 3, 5, 8, 4, 4, 6, 2];
%my code
total_price = 0;
for price = 1:length(prices)
total_price = total_price + prices(price);
end
disp(total_price);
average_price = total_price/numel(prices);
fprintf('Average Hair Cut Price is: %.3f\n', average_price);
%problem #5
new_prices = prices()-5;
disp(new_prices);
%fprintf('The new prices are: %.2f\n', new_prices);
%Revenue
total_revenue = 0;
total_revenue = sum(prices.*last_week);
fprintf('Total Revenue is: %.f\n', total_revenue);
%average revenue
average_revenue = total_revenue/7;
fprintf('The average revenue is: %.f\n', average_revenue)
% cuts_under_30 = [hairstyles[i] for i in range(len(hairstyles)) if new_prices[i] < 30]
indexes = new_prices < 30;
cuts_under_30 = hairstyles(indexes)
prices_under_30 = new_prices(indexes)
fprintf('Cuts under 30 :\n')
for k = 1 : length(prices_under_30)
fprintf('%s costs $%.2f\n', cuts_under_30{k}, prices_under_30(k));
end
fprintf('\n')

% cuts_under_30 = [hairstyles[i] for i in range(len(hairstyles)) if new_prices[i] < 30]
cuts_under_30 = hairstyles(new_prices < 30);

Then, to print to the command window:
fprintf("Cuts under 30 :\n")
fprintf('%.2f ', cuts_under_30);
fprintf('\n')

Or simply remove the semicolon at the end of the statement.

hairstyles = ["bouffant", "pixie", "dreadlocks", "crew", "bowl", "bob", "mohawk", "flattop"];
prices = [30, 25, 40, 20, 20, 35, 50, 35];
last_week = [2, 3, 5, 8, 4, 4, 6, 2];
total_price = sum(prices)
average_price = mean(prices)
new_prices = prices()-5;
total_revenue = sum(prices.*last_week)
average_revenue = total_revenue/7
cuts_under_30 = last_week(new_prices < 30) % the number of haircuts under $30
hairstyles (new_prices < 30) % the styles of haircuts under $30
new_prices(new_prices < 30)
