Hello, I'm a newbie to MATLAB and am having a problem with something which I believe should be quite simple.
I have a comlicated identity, the unknown of which I need in another equation. The code below shows a simplified version of what I'm trying to do.
clear all
clc
syms m
solve('m+6=4-m', m)
x=[0:1:10];
for i=1:11
y(i)=m*x(i)+5;
end
hold on
plot (x, y)
It's easy to see here that m = -1, and if I replace lines 3 and 4 with "m=-1;", I get my graph. However my identity is much more complicated than that shown and I can't rearrange it as "m=...". Can anyone help? I hope this was clear, please let me know if more information is needed.
These are the error messages I'm getting:
Error using sym/solve>getEqns (line 418)
List of equations must not be empty.
Error in sym/solve (line 226)
[eqns,vars,options] = getEqns(varargin{:});
Error in Test (line 4)
solve('m+6=4-m', m)

There are some syntax issues in your code. Check the following code
clear all
clc
syms m
m_ = solve(m+6==4-m, m);
x= 0:1:10;
y = zeros(size(x)); % pre-allocation
for i=1:11
y(i)=m_*x(i)+5;
end
hold on
plot (x, y)
