Note that conv2(double(im(:,:,q)),mask,’same’)./sz^2 is the same as conv2(double(im(:,:,q)),mask./sz^2,’same’) This is because the convolution and the multiplication commute. Thus, the convolution operation computes a local mean. Without the division, it would be a local sum. 0 solved Why is the output of `conv2()` is divided by `sz^2`?
If you wanted to be real fancy, you could write an anonymous function to do this since you can then use inputname to infer the name of the input variable. func = @(var)fprintf(‘\n%s size: %s\n’, inputname(1), num2str(size(var))) x = rand(10, 4); func(x) % x size: 10 4 You can also just use fprintf fprintf(‘\n%s size: … Read more
Looks like you are missing a closing parenthesis, at least, in the second to last line where you have .*sin((y).*sin(z), and missing a * (or another operator) between your )( in several lines. In MATLAB (A)(B) is not A*B. 8 solved What is the syntax error “Error: Unbalanced or unexpected parenthesis or bracket.”? [closed]
In Octave, you can decrease the size of the marker like this: x = 0:0.1:100; fx = rand(length(x), 1)’; plot(x, fx, “.”, “markersize”, 1) 2 solved Plotting discontinuous function in MATLAB/Octave
Each of the parameters are being used to find particular X and Y values. O changes from 0 to pi in steps of pi/8 while Vo, t and g remain unchanged. The t variable is simply an array from 0 to 5 in steps of 1 and so there are 6 time points defined all … Read more
