Plotting Symbolic Functions: Certainly we can also plot symbolic relationships. Since we have already defined the constants for use with f1(x), let’s use this function to do some simple plots. In particular, let’s plot f1(x), df1/dx, and over the range . We can do this as follows:...
The "int" + "vpa" functions use symbolic methods to evaluate the results and is efficient in cases where integral is computable in closed/analytical form which are less computationally intensive. The "vpaintegral" function uses numerical methods to solve the integral and is much more efficient in...

So I'm currently trying to explicitly integrate a function with four variables f(x,y,t,omega) w.r.t x and y. The differential of omega is defined as a function of x,y,t and omega. While initially I attempted to do this using the symbolic toolbox, unfortunately MATLAB is unable to...

please can someone help me to solve this problem: I want to integrate this function: exp(0.5*(1-((l-hm)/(2*H))-exp(-((l-hm)/(2*H))) I make this program: hm=400; H=50; symsl; H0=int(exp(0.5*(1-((l-hm)/(2*H))-exp(-((l-hm)/(2*H))),l,hm,700) but the...
