symbolic matrix
Creates a symbolic matrix M. The elements of symbolic matrices are symbolic scalars (cf. Sym).
Returns an empty matrix.
Returns a matrix with the elements from a matrix, vector or set a.
Returns a matrix with r rows and c columns, whose elements are different symbols named "b" appended by an index "ij" with i = 1,..,r, j = 1,..,c.
For vectorial r and c, it returns a matrix with length(r) rows and length(c) columns, whose elements are different symbols named "b" appended by an index "ij" with i = r(1),..,r(length(r)), j = c(1),..,c(length(c)).
// create matrix of zeros A = Zeros(3,3) // create a symbol x = Sym("x") // create matrix filled with the same "x" element B = Mat(x(ones(3,4))) // create matrix filled with different "xij" elements C = Mat("x",3,4) // create from string matrix D = Mat(["a","b";"c","d"]) // create (2,5)-matrix from vector E = Mat(Vec("v",10)) E = Reshape(E,2,5) |  |  |
