Hello,
Before i ask my question i want to mention that i am beginner level in matlab.
I wrote in matlab a simple program which is given below:
function [ output_args ] = Untitled( input_args )
for i=1:6
for j=1:30
k=1:24;
if 6<=k<17
if ruzgaruretimi(k,j)>sulamagider(k,j)
sebekein==sebekein
elseif ruzgaruretimi(k,j)<sulamagider(k,j)
if sdepo>0
sebekein==sebekein
sdepo==sdepo-1
elseif sdepo==0
sebekein==sebekein+15.708
end
end
end
end
end
end
I defined all veriables but i still get this error message:
Undefined function 'ruzgaruretimi' for input arguments of type 'double'.
Error in dnm (line 6)
if ruzgaruretimi(k,j)>sulamagider(k,j)
How can i solve it?
regards

Variables are assigned by "=", while "==" compares variables. sebekein==sebekein replies TRUE for all elements - I assume it is meaningless actually.

There are so many things wrong with your function that fixing the error you are getting is going to be of little value. If you are a beginner in MATLAB, you need to read the documentation. For example these lines:
k=1:24;
if 6<=k<17
% Do something
end
are not doing what you think they are doing.

You need to make sure that the function ruzgaruretimi are on your path. It should also expect double inputs. If it does, try to do
rehash toolbox
to refresh your toolbox cache.

Have you defined this variable inside the function? Having the variable in your MATLAB workspace is not sufficient.
You could declare ruzgaruretimi as a global variable, but I think it is probably better to either define it inside your function, or pass that variable to your function as an input argument.

Sorry, if it is a function, then what Honglei suggested is correct. I may have misunderstood that ruzgaruretimi is a matrix. If it is a matrix, then you have to make it a global variable, define it inside the function, or pass it as an input argument.
