WebValues need to be of type FloatingPoint which is a discriminated union that can represent not only float and complex but also vectors and matrices of the same. 1: 2: let symbols = Map.ofList [ "a", Real 2.0; "b", Real 3.0 ] Evaluate.evaluate symbols (1/(a*b)) // Returns Real 0.1666666667 (as float) Manipulating Expressions WebThis snippet adds the 'GetSlice' operation to Math.Net vector and matrix types. This makes it possible to get sub-vectors and sub-matrices using the convenient syntax (For vectors 'vect. [start .. end]` or 'vect. [start ..]' and for matrices 'mat. [r1 .. r2, c1 .. c2]' and similar). Vector and matrix extensions Examples of slicing
Webvar m = Matrix.CreateRandom ( 10, 10 ); // Extract the 2nd to the 5th row of m: var m1 = m [ new Range ( 1, 4 ), Range.All]; // Extract the odd columns: var m2 = m [Range.All, new Range ( 1, 10, 2 )]; // Extract the 4x4 leading sub-matrix of m: var m3 = m [ new Range ( 0, 3 ), new Range ( 0, 3 )]; You can also assign to ranges. http://www.fssnip.net/dQ/title/Slicing-for-MathNet-vectors-and-matrices
