Suppose I have an equation involve many letters:

    \begin{equation}
    \min   \|S-A\|_F^2  
    \end{equation}

How can I bold the letter in equation, such as S and A in the equation. We can \bm{A} for each letter in Equation. But any fast way since we may have a lot of letter in equation.

  • How about \mathbf ? – nidhin Oct 29 '18 at 18:24
  • for each letter like, \mathbf{A} and \mathbf{S}? I prefect some fast way, such as using some setting. bold letter appear, not one by one using \mathbf – jason Oct 29 '18 at 18:26

    \mathbf{S-A} should work. – nidhin Oct 29 '18 at 18:28

    \bm would embolden everything, so \bm{S-A} is not a solution. The solution is indeed \min\lVert \vc{S}-\vc{A}\rVert_F^2, where \vc is an alias for \bm: use semantically oriented commands. Being boldface is an attribute of the symbol, not of the formula. – egreg Oct 29 '18 at 18:49

Adding following line to the preamble worked for me to change the math font globally.

\DeclareSymbolFont{letters}{OT1}{cmr}{bx}{n}

But operators won't be bold. Adding following line made operators and numbers bold.

\DeclareSymbolFont{operators}{OT1}{cmr}{bx}{n}
