I want to change the symbolic variables in my matrix to numbers

To make it simpler to explain, I just want to plot the results of this final matrix. But it gives me zero as the answer because it is in a symbolic format. Is there a way to change it to the actual value ?

clear all ; close all; close ; clear
syms s
Expr = (sin(s));
F1 = int(Expr)

F1 = 

syms n 
expr2 = 1/n ;
F2 = int(expr2)

F2 = 

total = F2 == F1

total = 

final = isolate(total,n)

final = 

want2plot = subs(final,s,0:0.1:5)

want2plot =

Use the fplot function —

clear all ; close all; close ; clear
syms s
Expr = (sin(s));
F1 = int(Expr)

F1 = 

syms n 
expr2 = 1/n ;
F2 = int(expr2)

F2 = 

total = F2 == F1

total = 

final = isolate(total,n)

final = 

want2plot = subs(final,s,0:0.1:5)

want2plot = 

figure
fplot(rhs(final), [0 5])
grid
xlabel('s')
ylabel('n')
title('‘fplot’')

Alternatively —

nfcn = matlabFunction(rhs(final))

nfcn = function_handle with value:
    @(s)exp(-cos(s))

figure
plot((0:0.1:5), nfcn(0:0.1:5))
grid
xlabel('s')
ylabel('n')
title('‘matlabFunction’')

figure
plot(0:0.1:5, double(rhs(want2plot)))
grid
xlabel('s')
ylabel('n')
title('‘want2plot’')

EDIT — Added the ‘Alternatively —’ section.

Added independent variable to ‘want2plot’ and added titles.

Thank you very much!! That makes sense, i saw somewhere that you could use the rhs and lhs for stuff but didn't think of using it like this to get the answer.

As always, my pleasure!

(I added some asethetic tweaks to my original post. Code unchanged.)
