&lt;br /&gt;
In [[applied mathematics]], a &#039;&#039;&#039;damping matrix&#039;&#039;&#039; is a matrix corresponding to any of certain systems of linear ordinary differential equations.  &lt;br /&gt;
&lt;br /&gt;
A &#039;&#039;&#039;damping [[Matrix (mathematics)|matrix]]&#039;&#039;&#039; is defined as follows.  If the system has &#039;&#039;n&#039;&#039; [[Degrees of freedom (mechanics)|degrees of freedom]] &#039;&#039;u&#039;&#039;&amp;lt;sub&amp;gt;&#039;&#039;n&#039;&#039;&amp;lt;/sub&amp;gt; and is under application of &#039;&#039;m&#039;&#039; [[damping]] [[force]]s.&lt;br /&gt;
&lt;br /&gt;
Each [[force]] can be expressed as follows:&lt;br /&gt;
&lt;br /&gt;
: &amp;lt;math&amp;gt;f_{Di}=c_{i1} \dot{u_1}+c_{i2} \dot{u_2}+\cdots+c_{in} \dot{u_n}=\sum_{j=1}^n c_{i,j}\dot{u_j} \, &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
It yields in [[Matrix (mathematics)|matrix]] form;&lt;br /&gt;
&lt;br /&gt;
: &amp;lt;math&amp;gt;F_D=C \dot{U} \, &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where &#039;&#039;&#039;C is the [[damping]] matrix&#039;&#039;&#039; composed by the damping coefficients:&lt;br /&gt;
&lt;br /&gt;
: &amp;lt;math&amp;gt;C=(c_{i,j})_{1\le i\le n,1\le j\le m} \, &amp;lt;/math&amp;gt;&lt;br /&gt;
