Sorry, you cannot do that. If matrix is small split it in imaginary part and real part . This will double the dimensions. But this family of calculators you can have matrices with dimensions at most equal to three. Do the calculation by hand.

What you call the iota may be the key to enter imaginary parts of complex numbers. Please read your calculator's manual.

The summation function only works in the real mode, not the complex mode. You'll find that the same limitation applies to many other functions, such as the integration.

See page E-42 of this manual for the functions that are allowable in complex mode.

The fx-350MS does not have complex capabilities. You can do complex calculations the old-fashioned way, breaking each complex number into its real and imaginary components.

This calculator can do simply algebra with complex numbers-addition, subtractions, multiplications, extract the imaginary and real parts- but not much else. Sorry, calculating exponentials or complex numbers is not within its capabilities.

You need to be in complex mode before you can do any calculations involving complex numbers. Press MODE 2 to switch to CMPLX mode. When you're done, press MODE 1 to switch back to COMP mode. (Yes, the names are confusing. I didn't pick them.)

There isn't one. If you're entering a complex number in rectangular form, separate the real and imaginary parts with a comma (left of the 4). If you're entering a complex number in polar form, separate the magnitude and the angle with the angle symbol (2nd comma).

If you are using scientific calculator; there must be a symbol " ^ ". It is for power.

You can use it like this... 2^12=4096

If there isn't any such symbol... then it won't be easy.

2^12 = 4 ^ 6 = 16 ^ 3 = 16x16x16 = 4096

I hope this was helpful.

I am guessing, but, find the key that has a 3 to the left of the root symbol, looks like a check mark. Push it, then the number you want to take a cube root of, then enter.
