MATLAB: How to properly write this equation exp(x)cos(y)

equationmatrix

I wrote it like exp(x).*cos(y) but I kept getting "Matrix dimensions must agree" as output

This might be what you want,

[y,x]=meshgrid(-1:0.5:1,-2*pi:0.5:2*pi);
   exp(x).*cos(y)

BaconSwordfish. After many hours I finally got it. You need two new counters in a for loop with an if end statement like so assuming you already have x and y saved into arrays.

    for l=1:length(x) 
        if x(l)>0
            xQ14=x(x>0); %x is positive in quadrants 1 & 4
        end
        if x(l)<0
            xQ23=x(x<0);
        end
    end

MATLAB: How to plot this function

Try this instead:

x=0:10:200;
y=0:0.05:1;
[X,Y]=meshgrid(x,y);
Z=(-0.5)*X.*(X+1).*(X-1).*((Y.^X./X)-(2*(Y.^(X-1))./(X-1))+(Y.^(X-2))./(X-2)-2./(X.*(X-1).*(X-2)));
surf(X,Y,Z)
rotate3d on
