This element specifies properties of the matrix m, including the justification of the matrix and the layout of elements within the matrix. [Example:

<m:oMath>
  <m:r>
    <m:t>a+</m:t>
  </m:r>
  <m:m>
    <m:mPr>
      <m:baseJc m:val="top"/>
    </m:mPr>
    <m:mr>
      <m:e>
        <m:r>
          <m:t>1</m:t>
        </m:r>
      </m:e>
      <m:e>
        <m:r>
          <m:t>2</m:t>
        </m:r>
      </m:e>
    </m:mr>
    <m:mr>
      <m:e>
        <m:r>
          <m:t>3</m:t>
        </m:r>
      </m:e>
      <m:e>
        <m:r>
          <m:t>4</m:t>
        </m:r>
      </m:e>
    </m:mr>
  </m:m>
  <m:r>
    <m:t>+b</m:t>
  </m:r>
