Hello all,

I have some equations integrated in Matlab. One such set of equations are,

H2Ox = @(EA) -0.0023*(-8/(48000^8))*(((EA)-183000)^7);

H2Oz = integral(H2Ox, 183000, Inf);

Here there are no issues with integration, but I would like to plot the variations for integrating parameter EA. I don't know if Matlab provides the intervals to understand the change in values.

Is it possible to get the EA values as output ? in order to understand as how EA behaves ?

Kindly someone share the thoughts.

Thank you

ok. If you plot it a simple 2D plot, what would be the X and Y axes?

X - EA,

Y - Dependent variables like FE_H2O, CO2, so so on

在 MATLAB Online 中打开

Note that integral(H2Ox, 183000, Inf) = Inf !!

H2Ox = @(EA) -0.0023*(-8/(48000^8))*(EA-183000).^7;

H2Oz = @(y) integral(H2Ox, 183000, y);

y = 183000:100:300000;

plot(y,arrayfun(H2Oz,y))
