Function returns only one output at time


Tag: matlab

I have a problem with this function (I have very little experience with Matlab). The function is supposed to return 3 different arguments but always returns only one. I mean, to get Y out I have to remove Tot and Z from the output arguments! As it is now only Tot is returned.

function [Tot, Z, Y] = something( A )

%A = [1 2 3; 4 5 6; 7 8 9; 10 11 12];

Z=cumsum(A);             %cumulative sum of columns
Y=cumsum(A,2);              %cumulative sum of rows
Tot = sum(Z(:))+sum(Y(:));    %Total sum of Z+Y


Why is doing that ? What am I doing wrong, I need all 3 arguments out.


The proper call to receive all three arguments would be: [A, B, C] = something (X), where Tot would be placed into A, Z into B, and Y into C. If you just want Y, you can use the "tilde" operator to ignore other outputs: [~,~,C] = something(X).


Saving images with more than 8 bits per pixel in matlab

I need to save a set of pre-processing images in matlab, resulting in grayscale images. The problem is the fact that these pre-processed images have pixel values higher than 255. If I save them with imwrite() as, for instance, .PNG files, does matlab normalize the values to be in [0,255]...

Why can't I calculate CostFunction J

This is my implementation of CostFunctionJ: function J = CostFunctionJ(X,y,theta) m = size(X,1); predictions = X*theta; sqrErrors =(predictions - y).^2; J = 1/(2*m)* sum(sqrErrors); But when I try to enter the command in MATLAB as: >> X = [1 1; 1 2; 1 3]; >> y = [1; 2; 3];...
