If called as solve_sys(lhs, vars) the roots are found. If called as solve_sys(lhs, rhs, vars) the solutions to lhs = rhs for vars are found.

solve_sys(lhs, rhs, vars)

Arguments

lhs

Equation (or equations as row vector/1xn matrix)

rhs

Equation (or equations as row vector/1xn matrix)

vars

vector of variable names or symbols

Value

A list with solutions (with class caracas_solve_sys_sol for compact printing), each element containing a named list of the variables' values.

Examples

if (has_sympy()) { x <- symbol('x') exp1 <- 2*x + 2 exp2 <- x solve_sys(cbind(exp1), cbind(exp2), x) x <- symbol("x") y <- symbol("y") lhs <- cbind(3*x*y - y, x) rhs <- cbind(-5*x, y+4) sol <- solve_sys(lhs, rhs, list(x, y)) sol }
#> Solution 1: #> x = 2/3 #> y = -10/3 #> Solution 2: #> x = 2 #> y = -2
