Answer 1

[Walter Roberson]

max(YourImage)     %one of the projections
max(YourImage,2)    %the other projection

Answer 2

[Image Analyst]

What do you want to project - the max or the sum or the mean?

verticalProfile = max(grayImage, 2);
verticalProfile = sum(grayImage, 2);
verticalProfile = mean(grayImage, 2);
horizontalProfile = max(grayImage, 1);
horizontalProfile = sum(grayImage, 1);
horizontalProfile = mean(grayImage, 1);

For other arbitrary angles you can use radon().
