    LaTeX code in MS Word: Toggle TeX option doesn’t work on large equations

    MathType is a good piece of software as it allows to integrate LaTeX code into MS Word documents, but recently I encountered a problem using “Toggle TeX” option with large equations in MS Word 2010 (in both .doc and .docx formats). As for example, I can’t “Toggle TeX” equation of this size (Toggle Tex option merely doesn't work on the LaTeX code presented below):

    \[\begin{align}
    \beta^{\top}\Delta x_{t} &= \beta^{\top}\alpha\beta^{\top}x_{t-1}
    + \beta^{\top}\varepsilon_{t} \\
    \beta^{\top}x_{t} &= \beta^{\top}x_{t-1}
    + \beta^{\top}\alpha\beta^{\top}x_{t-1}
    + \beta^{\top}\varepsilon_{t} \\
    &= (I + \beta^{\top}\alpha)\beta^{\top}x_{t-1}
    + \beta^{\top}\varepsilon_{t} \\
    &= (I + \beta^{\top}\alpha)
    [(I + \beta^{\top}\alpha)\beta^{\top}x_{t-2}
    + \beta^{\top}\varepsilon_{t-1}]
    + \beta^{\top}\varepsilon_{t} \\
    &= (I + \beta^{\top}\alpha)^{2}\beta^{\top}x_{t-2}
    + (I + \beta^{\top}\alpha)\beta^{\top}\varepsilon_{t-1}
    + \beta^{\top}\varepsilon_{t} \\
    &= (I + \beta^{\top}\alpha)^{2}
    [(I + \beta^{\top}\alpha)\beta^{\top}x_{t-3}
    + \beta^{\top}\varepsilon_{t-2}]
    + (I + \beta^{\top}\alpha)\beta^{\top}\varepsilon_{t-1}
    + \beta^{\top}\varepsilon_{t} \\
    &= (I + \beta^{\top}\alpha)^{3}\beta^{\top}x_{t-3}
    + (I + \beta^{\top}\alpha)^{2}\beta^{\top}\varepsilon_{t-2}
    + (I + \beta^{\top}\alpha)\beta^{\top}\varepsilon_{t-1}
    + \beta^{\top}\varepsilon_{t}
    \end{align}\]

    But everything works fine with equations of smaller size like this:
    \[\begin{align}
    \beta^{\top}\Delta x_{t} &= \beta^{\top}\alpha\beta^{\top}x_{t-1}
    + \beta^{\top}\varepsilon_{t} \\
    \beta^{\top}x_{t} &= \beta^{\top}x_{t-1}
    + \beta^{\top}\alpha\beta^{\top}x_{t-1}
    + \beta^{\top}\varepsilon_{t}
    \end{align}\]

    or

    \[\begin{align}
    & \beta^{\top}x_{t} = \beta^{\top}x_{t-1}
    + \beta^{\top}\alpha\beta^{\top}x_{t-1}
    + \beta^{\top}\varepsilon_{t} \\
    & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, \,
    = (I + \beta^{\top}\alpha)\beta^{\top}x_{t-1}
    + \beta^{\top}\varepsilon_{t}
    \end{align}\]

    I do not experience any problems copy-pasting latex code for any size equation into MathType window directly – equations appear as they should. Limitation occurs only working with Toggle TeX option.

    Is there any way to use Toggle TeX with large equation sets as above or not? Maybe there are certain limitations in the size of equation that you can “toggle tex”. Your help is appreciated.

    I've already done that, but they have not replied, so I thought it is a good idea to search for a help here. Maybe they will reply later, maybe not, who knows.

    In the United States, this is the week of the Thanksgiving Holiday.
    Most colleges & universities are closed. I suspect the same is true for businesses catering to academic needs.

    Re: LaTeX code in MS Word: Toggle TeX option doesn’t work on large equations

    I’ve received an e-mail from Design Science. For those who will face the same problem, I’m pasting an answer:

    Hello,

    Currently, there is a limitation with the MathType add-in for Word that prevents the toggling of very large equations like this. We have entered this as a bug so that it can be addressed, but unfortunately there is no workaround for this. The details of the issue do not describe the size limit, but we can look into this further if you are interested in knowing this.
