Hi

I want to make a loop for the following expression:

location1=find ( ...
equation{1}<1e-1 & ... 
equation{2}<1e-1 & ...
equation{3}<1e-1);

each "equation {}" is a cell array and each cell includes a three dimensional matrix. I do not know how to and all of these equations in a loop way.

Thanks

Please provide more detail. Maybe a short example showing inputs and desired output.

Thanks for your attention. "equation{i}" gives me a three dimensional matrix of real numbers. So, in the aforementioned command, we have 3 matrices which are three dimensional. I need to find the places (in these three dimensional matrices) at which for all these three 3-dimensional matrices the value is less than one.

Thanks for your good response. The point is that I want to "and" all of these together. In addition, consider the number of cells should be defined during the code and before that I do not know how many cells I will have. So, I guess I need a for-loop which can "and" any number of matrices and find the locations at which the criteria I want is satisfied.

Regards
