pretty

Prettyprint symbolic expressions

pretty is not recommended. Use Live Scripts instead. Live Scripts provide full math rendering while pretty uses plain-text formatting. See What Is a Live Script or Function?

Syntax

pretty(X)

Description

pretty(X) prints X in a plain-text format that resembles typeset mathematics. For true typeset rendering, use Live Scripts instead. See What Is a Live Script or Function?

Pretty Print Symbolic Expressions

Pretty print symbolic expressions.

A = sym(pascal(2))
B = eig(A)
pretty(B)

A =
[ 1, 1]
[ 1, 2]

B =
 
 3/2 - 5^(1/2)/2
 5^(1/2)/2 + 3/2
 
/ 3   sqrt(5) \
| - - ------- |
| 2      2    |
|             |
| sqrt(5)   3 |
| ------- + - |
\    2      2 /

Pretty Print Long Expressions

Solve this equation, and then use pretty to represent the solutions in the format similar to typeset mathematics. For better readability, pretty uses abbreviations when representing long expressions.

syms x
s = solve(x^4 + 2*x + 1, x,'MaxDegree',3);
pretty(s)

/         -1         \
