I've also tried to use the function solve for this, however even if I construct the equations represented by the matrices A and b above, I'm having issues. para aquellos que instalaron matlab sin ninguno de sus complementos y nesecitan usar la fun.
#SYMBOLIC MATH TOOLBOX ERROR CODE#
Here is the code I'm attempting to execute (from the answer at the above link): A = Īnd the output is: ? Undefined function or method linsolve' for input arguments of type 'sym'. The toolbox uses the Golub-Welsch method, to compute all Gaussian quadrature. posible solucion a error: syms requires Symbolic Math Toolbox. Is using linsolve with sym variables only possible in R2013b? I've also tried it with my school's copy, which is R2012b. posible solucion a error: 'syms' requires Symbolic Math Toolbox. Copy and pasting the exact code and recieve the following: syms xexpr - 2 x/ ( 1 +x 2 ) 2 F int (expr) Error using sym/subsindex (line 855) Invalid indexing or function definition.
However, when I try to run the commands from the provided answer, or the linsolve help page, I get an error saying linsolve doesn't support arguments of type 'sym'. Trialing the symbolic toolbox and attempting to run the Indefinite Integral of Univariate Expression example from the int function documentation.
#SYMBOLIC MATH TOOLBOX ERROR UPDATE#
After the last update from MS -Feature update to Windows 10, version 1803 (known as April 2018)- Symbolic math toolbox crashes even with a simple line code (syms x). I asked a question a few days ago here and got an answer that seems like it would work- it involves using linsolve to find the solutions to a system of equations that are all modulo p, where p is a non-prime integer. Matlab crashes when I use symbolic math toolbox.
