Hi, please when i run my GUI interface, I have this error:
Error using repmat
Replication factors must be a row vector of integers or integer scalars.
Error in drawColormap (line 36)
coordX_Matrix = repmat(coordX_Matrix_t,y_samples,1);
Error in simul1>pushbutton100_Callback (line 416)
drawColormap(handles);
Error in gui_mainfcn (line 95)
feval(varargin{:});
Error in simul1 (line 42)
gui_mainfcn(gui_State, varargin{:});
Error in @(hObject,eventdata)simul1('pushbutton100_Callback',hObject,eventdata,guidata(hObject))
Error while evaluating UIControl Callback
the code of y_samples is:
coordX_Matrix_t = ones(1,x_samples);
ind = find(coordX_Matrix_t)-1;
coordX_Matrix_t = ((max_x * 2.0) / x_samples)*ind;
coordX_Matrix = repmat(coordX_Matrix_t,y_samples,1);
%coordX_Matrix = repmat(coordX_Matrix_t,1,y_samples);
coordY_Matrix_t = ones(fix(y_samples),1);
ind2 = find(coordY_Matrix_t)-1;
coordY_Matrix_t = ((max_y * 2.0) / y_samples)*ind2;
coordY_Matrix = repmat(coordY_Matrix_t,1,x_samples);
coordVectors = get(handles.figure1, 'UserData');
it=coordVectors.it;

Apparently y_samples is not a row vector of integers or an integer scalar.
If you want more meaningful help, have a read here and here. It will greatly improve your chances of getting an answer.

Hi, The problem appear in my interface when i click to Run simulation button. The color of axes changes to blue. can you help me how i solve this problem. I need that the color of axe remains colorless and the blue color disappear. This is the code of the gui interface:simul1.m The code of the drawColormap in the <file:drawColormap.m>

Thanks. BUt i stil have the same error: this is the syntax: coordX_Matrix_t = ones(1,x_samples); ind = find(coordX_Matrix_t)-1; coordX_Matrix_t = ((max_x * 2.0) / x_samples)*ind; coordX_Matrix = repmat(coordX_Matrix_t,y_samples,1); %coordX_Matrix = repmat(coordX_Matrix_t,1,y_samples); coordY_Matrix_t = ones(fix(y_samples),1); ind2 = find(coordY_Matrix_t)-1; coordY_Matrix_t = ((max_y * 2.0) / y_samples)*ind2; coordY_Matrix = repmat(coordY_Matrix_t,1,x_samples);
coordVectors = get(handles.figure1, 'UserData'); it=coordVectors.it; The same error appear when i run my interface.

Read the two links I posted. Also, you posted this as an answer instead of a comment. You should delete this answer and post it as a comment, after having read the two links I provided.

I didn't mean you should post a new question, I meant you should post this text as a comment and correctly format it. (use the {}Code button)

double(uint16(sqrt(3)*125))
Is 217. You multiply this by 2 and divide by 4, which gives you a non integer that cannot be used as a replication factor.
