"Error using /
Arguments must be numeric, char, or logical. "
I have a 64X1 matrix of vol_frac and particle_ratio each. 'c' goes from 1 to 64 using for loop. Please tell me what is going wrong and how to rectify it. I have tried writing "vf=vol_frac(c,1);" inside for loop so that vf isn't a matrix but still same problem.
mu_ratio=(1-(vol_frac(c,1)/0.605)*((particle_ratio(c,1))^1.2))^(-1.5125);

Try to make a MWE so we can run your code without any other dependencies and can reproduce your issue. The best way to do this is to use the code section in the editor and use the run button. That way you can make sure we will see the same error message as you do.

The equation is under For loop so need to extract single value from vol_frac matrix. Don't want matrix division.

Try
mu_ratio=(1-(vol_frac(c,1)/0.605).*((particle_ratio(c,1)).^1.2)).^(-1.5125);
Notice the dots! .* .^
Difficult to be certain though. You should upload enough program for us to test.

condition=readmatrix('cases.xlsx','Sheet',1,'Range','A2:C65');

use readmatrix function in place of readtable and run the code. The outputs from readtable are usually not numeric arrays
