Open in MATLAB Online Ran in: The fzero() function requires a function handle. For symbolic work use vpasolve() ThemeCopy symsp f=2-ellipticK(p) f = x0=0.1 x0 =0.1000 a = vpasolve(f, p, x0) a = 0.64385621914775464686672115765108 ...
In the 3rd Iteration x1 is size of 3x1 symfun and grad_x1 is size of 9x1 . so the line ThemeCopy tx1_temp=subs(dif_x1,x1-grad_x1*t); is throwing error as MATLAB is not able to resolve "x1- grad_x1*t". So make sure both x1 ...
MATLAB 2011a finds the (extremely complicated) symbolic solution whereas MATLAB 2010b just gave up. Here’s another one syms an1 an2; eq1 = sym('4*cos(an1) + 3*cos(an1+an2) = 6'); eq2 = sym('4*sin(an1) + 3*sin(an1+an2) = 2'); ...
syms is defined, I want find out what variables are defined in it.You can use "who" to find out what symbols are accessible in the current workspace, and you can use class() to find out which class the variable is; or you can use isa(varible, 'sym') to test if ...

She works and speaks in TypeScript, Java, Clojure, Scala, Ruby, Elm etc etc. Her real love is systems thinking in symmathesy (a learning system made of learning parts). She works at Honeycomb.io because our software should be a good teammate and teach us what is going on. If you'...
To see what value is actually represented in a double or single, Symbolic Toolbox is very helpful. But, be sure to provide the 'f' option to get an exact conversion of the represented value to symbolic. ThemeCopy format long g u1Sym = sym(u1,'f'), u2Sym = sym(u2,'f'), diffe...
There is an example code, pardiso_unsym_c.c, in the MKL distribution, in the directory .../mkl/examples/solverc/source. You can modify it to read the matrix data from your data files and compute and print the residuals. If you see the same behavior (very different norm of res...
