MATLAB: Caught unexpected fl::except::IInternalException

errorImage Processing Toolbox

When I am executing the following command then I am getting an error message:

>> A = imread('image.png');

>> imshow(A)

>> Caught unexpected fl::except::IInternalException

Well, for me, it happened due to the graphics driver issue. The OS is ubuntu 16.04 LTS. To solve this problem, type:

opengl info

There, Matlab will give you low-level graphics troubleshooting methods.

The method of starting Matlab with software OpenGL solved my problem:

rik@ideapad:~$ matlab -softwareopengl

MATLAB: Do I see the error “Caught unexpected fl::except::IInternalException” when using the “plot” function

This error might appear if you have another function named "plot" on your path. Execute the following line to identify all functions named "plot" on your path.

>> which -all plot

If there is a user-defined function listed above the built-in, it may need to be renamed or removed from your path.

Note that you may see a number of other plot functions that are located in the MATLAB install directory. This is expected. They implement specific functionality for other built-in classes.

MATLAB: Caught in loop

And some cleanup:

...
% Vectorization of the "for i=1:N_i;" loop:
r = (0:N_i) * dr;
c = zeros(N_i, N_t - 1);  % Pre-allocate!
c(:, 1)       = c_inf;
c(r < a_0, 1) = c_s;
...
dr3 = dr ^ 3;
...
  % Reduce repeated calculations inside the "for j = 1:N_t -1" loop:
  ajp1   = a(j) +dt*beta*dc_dr;
  a(j+1) = ajp1;
  tmp1   = (a(j)^2) * (alpha-1) * (ajp1-a(j)) / (2 * dr3);
  for i = 2:N_i - 1
    if r(i) > ajp1
      tmp2 = rho / (i-1) + tmp1 / ((i-1)^2);
      d = rho - tmp2;
      e = 1 - 2 * rho;
      f = rho + tmp2;
      c(i, j+1) = d*c(i-1,j) + e*c(i,j) + f*c(i+1, j);
    elseif r(i) == ajp1
      c(i, j+1) = c_a;
    else
      c(i, j+1) = c_s;
    end
    % disp(c(i,j));
  end
