An easy to use uncertainty propagation calculator that uses the partial derivatives method to propagate uncertainties. Khmer civ 6. Accepts input in the form of an equation, variable values, and variable uncertanties, and gives output in the form of the equations used to generate the final uncertainty in latex or libremath. In my office my team and I are going to type texts in the future which will include mathematical signs. Two programs are being proposed: LibreOffice Writer + Math or Microsoft Office + MathType. Math is a formula editor module included with LibreOffice that allows you to create or edit formulas (equations) in a symbolic form, within LibreOffice documents or as stand-alone objects; example formulas are shown below.

Available for all kinds of platforms; enjoy group chat; support voice,photo,video and text messages.

WeChat Official Accounts Platform, provides the individual, businesses and organizations with a new service platform for business services and user management. Weixin is the version for mainland users, while WeChat is designed for overseas users, and they don’t belong to the same system or servers. Though they have similar interfaces and many common functions, these two apps are different from each other in several aspects.

This tutorial tells about how to write matrix expressions in LibreOffice Math and Writer, by examples. This tutorial is a continuation from the previous LibreOffice Math Introduction article. Here, we provide 12 examples with source code (markup code) for each of them. And we collect the codes summary at the end. We hope this helps you a lot.

Tool Needed

When you open LibreOffice Math, see Elements Toolbox > visit Formats > select Matrix.

For First Timers

Result:
This is the sample result, the simplest form of matrix:

Source code:
This is the source code (markup code) of that matrix.

matrix{a # b ## c # c}
LibreOffice Math:
You may either using LibreOffice Math to write that matrix expression like this ..

LibreOffice Writer:
.. or write that matrix expression directly into LibreOffice Writer by visiting menu Insert > Object > Formula.

Example 1

Result:

Source code:
left ( { matrix{a # b ## c # c} } right )
Explanation:
This code gives the basic matrix a pair of brackets. You may choose it from Brackets.

Example 2

Result:
Source code:
M = left ( { matrix{a_{1,1} # b_{1,2} ## c_{2,1} # d_{2,2}} } right )
Explanation:
This code adds subscript coordinate (row, col) to each matrix member.

Example 3

Result:

Source code:
M = left ( { matrix{1 # 2 ## 3 # 4} } right )
M = left ( { matrix{-1 # -2 ## -3 # -4} } right )
Explanation:
To write negative numbers, add minus sign right before every number.

Example 4

Result:
Source code:
M = left ( { matrix{{1 over 2} # {1 over 3} ## {1 over 4} # {1 over 5}} } right )
Explanation:
To write division/fraction inside a matrix, use “over” command.

Example 5

Result:

Source code:
M = left ( { matrix{1 # 2 # 3 ## 4 # 5 # 6 ## 7 # 8 # 9} } right )
N = left ( {matrix { 1 ## 2 ## 3} } right )
Explanation:
To write (x,y) matrix, pay attention to # and ##, while # indicating same line space, and ## indicating a line break inside a matrix.

Example 6

Result:
Source code:
A + B = {left ( {matrix{ 1 # 2 ## 3 # 4} } right )} + { left ( {matrix{ 5 # 6 ## 7 # 8} } right ) } = { left ( {matrix{6 # 8 ## 10 # 12} } right )}
Explanation:
An example for matrices addition operation. Maths

Example 7

Result:

Source code:
A = left ( {matrix{ a_{11} # a_{12} # dotsaxis # a_{1n} ## a_{21} # a_{22} # dotsaxis # a_{2n} ## dotsvert # dotsvert # dotsdown # dotsvert ## a_{m1} # a_{m2} # dotsaxis # a_{mn}} } right )
Explanation:
An example for a matrix with dots members. Pick the dots from Others category.

Example 8

Result:
Source code:
left ( {matrix{1 # 2 # 3 ## 4 # 5 # 6} } right )^{ T } = left ( {matrix{1 # 4 ## 2 # 5 ## 3 # 6} } right )
Explanation:
To write superscript “T”, just add “^” (caret) right between the matrix and the “T”.

Example 9

Result:

Source code:
left ( {matrix{a # b # c ## d # e # f} } right ) cdot left( {matrix{u # v ## w # x ## y # z} } right ) = left ( {matrix{au + bw + cy # av + bx + cz ## du + ew + fy # dv + ex + fz} } right )
Explanation:
Another example for matrices equation in an multiplication operation.

Example 10

Result:
Source code:
left ( {matrix{x” ## y”} } right ) = left( {matrix{cos %theta # sin %theta ## -sin %theta # cos %theta} } right ) left( {matrix{x ## y} } right )
Note:
The code to represent theta character is %theta.

Example 11

Result:

Source code:
M = left ( { matrix{ color magenta {1} # color magenta {2} # color magenta {3} ## 4 # 5 # 6 ## 7 # 8 # 9} } right )
N = left ( { matrix{ color magenta {1} # 2 # 3 ## 4 # color magenta {5} # 6 ## 7 # 8 # color magenta {9}} } right )

Explanation:
See the

Libre Maths

color magenta {} code. You may change the magenta color name into green, blue, red, or yellow.

Example 12

Result:


Source code:
left ( {matrix{8 # 12 # 3 ## 4 # 4 # 9} } right ) = left ( {matrix{8 # 6x # z-y ## y+1 # 4 # 9} } right )
Explanation:
Another example about matrices equation.
