In sentences matrices too close to other lines

Question

In my tex line spaces are 1.5 but if I write matrices in a sentence, these matrices are closer to lines than normal.

Answer 1

It really makes no sense to typeset column matrices inline, you should use a horizontal layout or use display math, however if you really do want to do this, the spacing used when things are too big to fit in \baselineskip spacing is \lineskip so while increasing the baselineskip you might also want to increase \lineskip up from its usual value of 1pt to, say, 3pt.

Answer 2

As David writes, you shouldn't use column matrices in inline text.

Here is one way of doing it:

\documentclass{article}

\usepackage{amsmath}

\newcommand*\spc{1ex}

\begin{document}

\section*{First option}
Something $b' = \begin{bmatrix}b_{1} & b_{2} & \cdots & b_{k}\end{bmatrix}_{k+1}$ and $x' = \begin{bmatrix}x_{1} & x_{2} & \cdots & x_{t}\end{bmatrix}_{t+1}$ something.

\section*{Second option}
Something
\begin{equation*}
  b' = \begin{bmatrix}b_{1}\\[\spc] b_{2}\\[\spc] \vdots\\[\spc] b_{k}\end{bmatrix}_{k+1}
  \qquad \text{and} \qquad
  x' = \begin{bmatrix}x_{1}\\[\spc] x_{2}\\[\spc] \vdots\\[\spc] b_{t}\end{bmatrix}_{t+1}
\end{equation*}
something.

\end{document}
