As a general rule (not 100%), any Mathematica function that ends in Form (e.g. MatrixForm, TableForm) is for display purposes only. When the front end "sees" MatrixForm, it creates a special "object" that makes the pretty display. If you try to do subsequent computations on that ...
If then is a special unitary matrix. The product of two unitary matrices is another unitary matrix. The inverse of a unitary matrix is another unitary matrix, and identity matrices are unitary. Hence the set of unitary matrices form a group, called the unitary group. ...
For example, the 3 × 3 unit matrix has the form (100010001) ; note that it is not a matrix all of whose elements are unity. Giving such a matrix the name 1, (2.32)1A=A1=A. In interpreting this equation, we must keep in mind that unit matrices, which are square and therefore...
Although the FID signal sϕ(t) appears in the time domain, it represents the Fourier domain projection data. Therefore, the projection data pϕ(x′) are obtained through the Fourier transform of the FID signal as (56)pϕ(x′)=F[sϕ(t);t→x′]. The basic form of projection ...
要是半年前有这个网站的话,我每个星期可以多抽出至少两个小时的时间来更新Blog。试着在Algebra里输入matrix[1,3,-2,5_3,5,6,7_2,4,3,8],然后选Find Reduced Row Echelon Form,然后点Answer……爽死了!
A CAL tutor for matrix theory is presented in this paper, in the form of Mathematica Notebooks. This constitutes one of a list of specific A-level mathematics core options required by science and engineering departments. The module has been written so as to recognize students errors and advise...

We are interested in the study of the sum E + F and the product E * F , when E and F are of the form s ξ, or s ξ ° , or s ξ ( c ) . Then we deal with the identities ( E + F )(Δ q ) = E and ( E + F )(Δ q ) = F . Finally we consider matrix ...
When using Mathematica, the routine MatrixExp[, ] gives the result directly in terms of RootSum[, ]. The three diagonal generators are λ3=diag(1,−1,0,0),λ8=diag(1,1,−2,0)/3, and λ15=diag(1,1,1,−3)/6. The remaining 12 generators have two non-zero entries either ...
