Age-structured differential equation model

Hi,
        I have a model consisting 9 differential equations. Now the whole population is divided into 10 age class, and each age class repeat those 9 differential equations. So full model is all together 90 equations. Note that these 9 equations are basically repeated of 10 times with some interactions terms of populations.

Now, if I write all 90 equations even with 'for'-loop, it takes long time to compute in Matlab. Is there any other way that we can do it?

Any suggestion would be great!

thanks,
Hato
