Matrix Calculations
Press to enter Matrix mode.
Before starting matrix calculations, you have to create one matrix
or a maximum of four matrices named A, B, C and D at one time.
The matrix dimension can be up to 4x4.
The matrix calculation results are stored into the MatAns memory
automatically. You can use the matrix MatAns memory for any
subsequent matrix calculations.
Creating a Matrix

! You can leave out the n in the Integration expression and the
calculator will automatically substitute a value for n.
! The smaller the entered value n is, the longer the calculation time will be
with more accurate results, the larger the entered value n is, the shorter
the calculation time will be with comparatively less accurate results.
! When performing integration calculations with trigonometric functions,
select radian (Rad) as the angle unit setting.
! Log
a
b, i~Rand(, Rec( , Pol(, ∫(, d/dx(, ∑(, ∏(, Max( and Min( functions
cannot join in integration calculations.
! A “Time Out” error occurs when an integration calculation ends without
the ending condition being fulfilled.
! You can cancel the processing of integration calculation by pressing
the key.
Example:
Perform the integration calculation for, with n = 4.
