I want to solve H for N=[1:7]. This however results in the warnings ''Warning: 7 equations in 1 variables.'' and ''Warning: Explicit solution could not be found.'' I've tried using a for loop but I need to plot (N, H) and with a loop the values of H overwrite eachother. Is there a way to solve H for different values of N? > > Regards, > > Jurjen
Multiplying with the denominator (6.*H.^2+12.*Be.*H+6.*Be.*T), you get a polynomial of degree 4 in the unknown H. Specify numerical values for the known constants and use "roots" to solve.
