MATLAB: How to convert a matrix like this

settdiff

Hello everyone, I need a help with this problem. I would like to convert a matrix to another one, like the following examples: A=[1;2;3;0;5;7]—–>A=[1;2;3;5;7] B=[0;1;3;4;5;6]—->B=[1;3;4;5;6] That means I have a new matrix without 0. Thank you very much!

Try this:

A(A==0)=[]

How about

ux = [1 0 -1 0 1];
uy = [0 1 0 -1 0];
% The order is CRU GPCC UDEL APH anticlockwise starting on positive x axis.
MAEx = [3.5 0 -0.5 0 3.5];
MAEy = [0 2 0 -8 0];
MBEx = [2.5 0 -2 0 2.5];
MBEy = [0 5 0 -4 0];
MDx = [0.1 0 -1.5 0 0.1];
MDy = [0 1 0 -2 0];
figure(1)
hold on
for i = 1:8
   plot(i*ux,i*uy,'k--')
   plot(MAEx,MAEy,'r',MBEx,MBEy,'b',MDx,MDy,'g','LineWidth',2)
end
text(8,0,'CRU')
text(-2,9,'GPCC')
text(-10,0,'UDEL')
text(-1,-9,'APH')
legend(' ','MAE','MBE','MD')
axis([-10 10 -10 10])
axis equal
axis off

MATLAB: What means this

iter,eps: iter is number of iterations. eps stand for a small value. So your code runs either for 10 iterations or till the error goes less than given eps.
x=-2:0.01:2: This will create a array x from -2 to +2 with a difference of 0.01
plot(x,y1,'-b'): This will plot the values of array x wrt to array y1.
err : This is error variable.
at last >fprintf('%2.0f&10.4f%10.4f%10.4%f10.4f/n', result): this is to print the respective values on the screen i.e on command window.

MATLAB is an easy language. You can check all those your self with out asking these simple questions.
