from a python code to matlab code

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);
255
average_price = total_price/numel(prices);
fprintf('Average Hair Cut Price is: %.3f\n', average_price);
Average Hair Cut Price is: 31.875
%problem #5
new_prices = prices()-5;
disp(new_prices);
25 20 35 15 15 30 45 30
%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);
Total Revenue is: 1085
%average revenue
average_revenue = total_revenue/7;
fprintf('The average revenue is: %.f\n', average_revenue)
The average revenue is: 155
% 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)
cuts_under_30 = 1×4 cell array {'bouffant'} {'pixie'} {'crew'} {'bowl'}
prices_under_30 = new_prices(indexes)
prices_under_30 = 1×4
25 20 15 15
fprintf('Cuts under 30 :\n')
Cuts under 30 :
for k = 1 : length(prices_under_30)
fprintf('%s costs $%.2f\n', cuts_under_30{k}, prices_under_30(k));
end
bouffant costs $25.00 pixie costs $20.00 crew costs $15.00 bowl costs $15.00
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);

It didn't work....Here is the whole code I am working on from Python...
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
%cuts_under_30 = ;
% for cuts_under_30 = 1:numel(hairstyles)
% i = hairstyles(cuts_under_30);
% if new_prices < 30
% end
% disp(cuts_under_30)
fprintf("Cuts under 30 :\n")
fprintf('%.2f ', cuts_under_30);
fprintf('\n')
