We offer numerical computational services. If we find obtaining an analytical expression of a differential is easy when we are asked to differentiate a function, we first obtain an analytical expression and then compute a numerical value unless otherwise requested. We apply the same rule when we try to obtain integrals or solutions of various equations. If an analytical expression is not available we will first investigate a behavior of the function before evaluating a differential numerically when we compute numerical differentiation. After this we determine an appropriate interval for the numerical computation to minimize error. We apply same rule to other computations if we think it is necessary.
We may help our customers to formulate equations in the case if our customers do not have any specific equations but they can describe the relationships among variables and how they affect the result.
Below is a list of typical computations we can offer. If you want us to compute something that is not in the list below, please send us an inquiry. We might be able to extend our services since we do write programs when it becomes necessary. We would like to note that the owner of CRInternational has experiences over 25 years in technical and scientific computations and over 15 years in physical oceanographic researches with several papers published in oceanographic journals in Japan and U.S.A.
*Least square approximation to various mathematical functions
We separated our services into several categories for the sole purpose of introducing our services in an organized manner. To serve your needs we do combine our services in different categories.
