The error message you’re encountering seems to suggest that there’s an issue occurring in a MATLAB script or function related to the contour function. Specifically, it looks like the error originates from contourHGUsingMATLABClasses which is an internal function called by the contour command.
Here are some steps to troubleshoot and resolve this issue:
Check Your Data:
- Ensure that the matrices you are passing to the
contourfunction (typically a grid of Z values corresponding to X and Y) have compatible dimensions. The matrices should be two-dimensional, and their sizes should match appropriately.
- Ensure that the matrices you are passing to the
Input Format:
- Confirm that you are using the correct format for your inputs in the
contourfunction. For example:[X,Y] = meshgrid(xValues, yValues); % Create a grid of X and Y values contour(X, Y, Z); % Where Z is a matrix of same size as X and Y
- Confirm that you are using the correct format for your inputs in the
Valid Data Range:
- Make sure that your data does not contain NaN or Inf values, as these can cause issues when plotting contours.
Examine Line 65 in Your Script:
- Look at what is happening on line 65 of your code (
Untitled). This line likely contains your call to thecontourfunction or its parameters—check for any mistakes there.
- Look at what is happening on line 65 of your code (
Example Code Structure: Here’s a simple example of how to correctly use
contour. You can adapt this based on your specific needs: “`matlab x = linspace(-3, 3, 100); y = linspace(-3, 3, 100); [X,Y] = meshgrid(x,y); Z = sin(sqrt(X.^2 + Y.^2)); % Example function
contour(X,Y,Z); title(‘Contour Plot’); xlabel(‘X-axis’); ylabel(‘Y-axis’); “`
Debugging Tools:
- Use MATLAB’s debugging tools (like breakpoints) to step through your code and inspect variables just before the error occurs.
MATLAB Documentation:
- If you continue having trouble with specific parameters or options within the
contourfunction, refer back to MATLAB’s documentation for additional details about usage:doc contour
- If you continue having trouble with specific parameters or options within the
If you provide more context regarding what you’re trying to plot and what your data looks like (or share relevant portions of your code), I may be able to give more tailored advice!
