Can it do complex matrix calculation?

[@equaser]

No

[@游忠煌-w2e]

​@@equaserThank you very much for your reply.

[@kadarislam8869]

how can i solve equation in complex mode
like what is the value of x^4-4x^3+6x^2-4x+5 if x=2+i?

[@equaser]

you can't. this calculator has polynomial solver which can give you real and imaginary solutions but cant' solve complex exponential. Use wolfram Alpha www.wolframalpha.com/input?i=what+is+the+value+of+x%5E4-4x%5E3%2B6x%5E2-4x%2B5+if+x%3D2%2Bi

[@Lifewithcats...]

You can!! You have to go in variable and then select x then type edit and put the magnitude of x and then go back and then just write this equation (using x) and You'll get your ans!!
