已知矩阵设AX=A+2X,求X.
举一反三
- 已知[img=52x29]18038be96ed0534.png[/img],[img=115x51]18038be97866e95.png[/img],在MATLAB中若想由x生成矩阵A可调用命令 A: A=[x,x.^2,x.^3] B: A=[x,x^2,x^3] C: A=[x;x.^2;x.^3] D: A=[x;x^2;x^3]
- 已知[img=52x29]1802e9891f49f72.png[/img],[img=115x51]1802e989277fcbc.png[/img],在MATLAB中若想由x生成矩阵A可调用命令 A: A=[x,x.^2,x.^3] B: A=[x,x^2,x^3] C: A=[x;x.^2;x.^3] D: A=[x;x^2;x^3]
- 已知[img=52x29]1803bbd8531a1be.png[/img],[img=115x51]1803bbd85b65619.png[/img],在MATLAB中若想由x生成矩阵A可调用命令 A: A=[x,x.^2,x.^3] B: A=[x,x^2,x^3] C: A=[x;x.^2;x.^3] D: A=[x;x^2;x^3]
- 三个矩阵中,已知A、B已知,求X,且AX=B,则有
- 设全集U={2,4,3-x},M={2,x2-x+2},∁UM={1},求x.
