Error using exponents in a small mathematical equation
显示 更早的评论
It seems I've run into a problem with a mathematical equation A=(-3.5*a)^3+(exp^7)/ln(524*a)+206^1/3 gives Error using exp Not enough input arguments.

exp^7 -> exp(7) and ln(524*a) -> log(524*a)
A = (-3.5*a)^3 + exp(7)/log(524*a) + 206^1/3 ;

Please, use the documentation. The natural logarithm function in matlab is called log (and 10 based logarithm is log10)

You are getting the error because you have used implicit multiplication, but MATLAB interprets this as indexing. The syntax you use here is for indexing into c, not for multiplication with some other value:
2.9^c(16+...
If you want to multiply these values, then you need to specify this:
2.9^c * (16+...
