Why do I receive an error when trying to set the grid spacing in the PDETOOL within the Partial Differential Equation Toolbox 1.0.5 (R14)?

When I try to change the grid spacing within the PDETOOL using the following steps:

1. Type

pdetool

in the command window.

2. Select "Options -> Grid Spacing...".

3. Deselect "Auto", and change the data in the field to be, for example, "1:10".

4. Click "Apply".

I receive a dialogue window saying

 Cannot evaluate edit field input.

This problem has been fixed in the Partial Differential Equation Toolbox 1.0.6 (R14SP1). If you are using the Partial Differential Equation Toolbox 1.0.5 (R14), to work around this issue, perform the following steps:

1. Type "edit pdespdlg" in the command window.

2. In pdespdlg.m, change line 29 from:

s=m(i,:);

to:

s = eval(m(i, :));

3. Click the "Save" button.

4. Rehash your toolbox path cache using REHASH TOOLBOXCACHE to cause MATLAB to recognize the change.
