assignment to variable in symbolic expression
Posted:

Hi, I just started using symbolic toolbox, hope my question is not too basic... I've done some calculations in Mupad:
Mupad eq1 := solve(ode(v''(z) = 1/15*z*(11/(2*a)z/2), v(z))) > C3 + C2*z + z^4/360  (z^3*(2*a  1))/(180*a) C3 := 0 solve(eq1,C2)  Now I want to do the same in MATLAB (because this is the only sybolic calculation that has to be done) MATLAB >> eq1 = dsolve('D2y = 1/15*z*(11/(2*a)z/2)','z') eq1 = z^4/360 + (1/(180*a)  1/90)*z^3 + C5*z + C6 ?  so how do I assign a value to C6 and solve the equation?
thanks in advance, martin
