matlab常用函数之solve

调用格式:

• S = solve(eqn,var)solves the equation eqn for the variable var. If you do not specify var, the symvar function determines the variable to solve for. For example, solve(x + 1 == 2, x) solves the equation x + 1 = 2 for x.
• S = solve(eqn,var,Name,Value)
• Y = solve(eqns,vars)
• Y = solve(eqns,vars,Name,Value)
• [y1,...,yN] = solve(eqns,vars)
• [y1,...,yN] = solve(eqns,vars,Name,Value)
• [y1,...,yN,parameters,conditions] = solve(eqns,vars,'ReturnConditions',true)

syms x
eqn = sin(x) == 1;
solx = solve(eqn,x)
%answer:solx = pi/2
