Ran in:
%Hello, this is very simple code but I am completey new to MatLab. Help!
points = [1:3]
points = 1×3
1 2 3
color = ["r", "g", "b", "m", "b"];
% Create a string variable that contains the name of the directory you
% created where you will writeout the plots
Outputfigures ='C:\Users\sfai\Documents\MATLAB\OutputFigures'; %I am not sure if this is what is meant by directory;
for i=1:3
h=figure
plot(points,points,color(i))
xlabel('X')
ylabel('Y')
title(strcat({'Figure # '}, num2str(i)))
%saveas(h,sprintf('OutputFigures/FIG%d.png',i));
%^^^This saves the titles with the correct names, but I was
%instructed to use a method that "concatenates strings to create the correct file and folder path"
%saveas(gcf, [strcat('Figure #', num2str(i), '.png')]);
%^^^This saves the titles with the correct names, but it saves
%it to the current folder.
%So what's the best way to save these figures with the correct names and file location?
end
h =
Figure (1) with properties: Number: 1 Name: '' Color: [1 1 1] Position: [671 661 577 433] Units: 'pixels' Show all properties
h =
Figure (2) with properties: Number: 2 Name: '' Color: [1 1 1] Position: [671 661 577 433] Units: 'pixels' Show all properties
h =
Figure (3) with properties: Number: 3 Name: '' Color: [1 1 1] Position: [671 661 577 433] Units: 'pixels' Show all properties

print(gcf,strcat(Outputfigures,num2str(i),'.png'),'-dpng'); % saving as a png

Thank you, I had issues with my string variable of the folder I wanted to save it in, when I did Outputfigures = 'Outputfigures/';, it works!
