ezmeshcArray multiplication, division, and exponentiation are always implied in theexpression you pass to ezmeshc. For example, the MATLAB syntax for a mesh/contour plot of the expression,sqrt(x.^2 + y.^2);is written as:ezmeshc('sqrt(x^2 + y^2)')That is, x^2 is interpreted as x.^2 in the string you pass to ezmeshc.ExamplesCreate a mesh/contour graph of the expression,f( x,y)=y---------------------------1 + x 2 + y 2over the domain -5 < x < 5, -2*pi < y < 2*pi:ezmeshc('y/(1 + x^2 + y^2)',[−5,5,−2*pi,2*pi])Use the mouse to rotate the axes to better observe the contour lines (thispicture uses a view of azimuth = -65.5 and elevation = 26).y/(1 + x 2 + y 2 )0.505−0.550y−5−50x2-143
