Geogebra 解線性變換

octave 矩陣表示法
mirX=[1 0; 0 -1]

maxima 矩陣表示法
mirX:matrix([1,0],[0,-1])

Geogebra 矩陣表示法
mirX={{1,0},{0,-1}}

Geogebra 一次輸入很多指令
Execute[
"{ }",
"{ }",
"{ }"
  ]

 Execute[{
"mirX={{1,0},{0,-1}}",
"mirY={{-1,0},{0,1}}",
"mirO={{-1,0},{0,-1}}",
"P=(1,2)",
"mirX*P",
"mirY*P",
"mirO*P"
}]


Execute[{
"M={{6,0},{0,6}}",
"N={{1,1/2},{0,1}}",
"P={{1,0},{1/3,1}}",
"Q={{-1,0},{0,-1}}",
"X=(1,1)",
"MX=M*X",
"NX=N*MX",
"PX=P*NX",
"QX=Q*PX",
"T=Q*P*N*M"
}]
