Can anybody help me to integrate & plot in the following format, i.e. contains multiple variables?:

z = 0:0.1:10;

a = -0.5:0.1:1;

x = 0:0.1:2;

y = 2*exp(-0.5*z) + x;

I = 0.2 ∫(0.5*(a-y)+0.3) dx

integration limit : 0 to x

plot (I,x);

@Dyuman Joshi —

‘Also, How do you check a function's efficiency? Just checking it's time to run a sample of code?’

That is how I usually do it. The timeit approach is most accurate, however I usually just use tic and toc. and occasionally the profile function, depending on the information I am interested in.

@Dyuman Joshi @Star Strider @Torsten glad to see your fruitfull discussion. Thanks, I'll go through it. I wish to apply this kind of logic in some other codes & if I face some problem, I'll ask.
