Text Formatting ⇒ Interesting problem i have formating text

[thedreamshaper]

I am writting alot about statistics, and thereofre also Matrices and Vectors. To get a consistent way of using my notation i want to make some commands i could simply write before and after the expressions which are vectors or Matrices.

rules:
-Matrices and Vectors are both in bold
-Matrices are capital letters, vectors are not

Now i figured i would use the \newcommand command to create these.

Code: Select all

\newcommand{\bm}{}
\newcommand{\bv}{}

bm and bm being "begin matrix" and "begin vector".

Is it possible to put my rules into these commands ?

I havent been able to figure out how to do so.


Thanks!

You were close. I suggest you use something like this:

Code: Select all

\newcommand{\bv}[1]{\ensuremath{\boldsymbol{#1}}}
\newcommand{\bm}[1]{\ensuremath{\boldsymbol{\uppercase{#1}}}}

In your LaTeX code, you can now write \bv{x} to produce a vector x and \bm{a} to produce an uppercase matrix A

Thanks Frits, exactly what i needed


i modified your code slightly to force vectors to be lower case as well.

Code: Select all

\newcommand{\bv}[1]{\ensuremath{\boldsymbol{\lowercase{#1}}}}
\newcommand{\bm}[1]{\ensuremath{\boldsymbol{\uppercase{#1}}}}
