In the most recent two answers I have posted to Matlab answers (here, here), I have used the equation editor (Sigma, in the Matlab Answers toolbar) in my answer. The equations display correctly while I am still working on my answer, while I am using the eq.editor and after I close it, but after I submit my answer, the equation does not look right. It displays as white space or as a rectangle of pixel noise. I observe this issue when viewing my answers in Firefox and in Edge. Some simple equations display correctly.
Here are examples, in pairs. The "A" version the text I enter in the editor. The "B" version is the equation, actually composed in the editor. For me, eq.1B displays correctly, but eqs. 2B and 3B display as white space only.
b_0=a_0+a_1+a_2 (eq. 1A)
(eq. 1B)x=\frac{-b\pm \sqrt{b^2-4ac}}{2a} (eq. 2A)
(eq. 2B)y_1(k)=b_0x(k)+b_1x(k-1)+b_2x(k-2)-a_1y_1(k-1)-a_2y(k-2) (eq. 3A)
(eq. 3B)Has anyone else noticed this or have a solution? Thank you.
