We provide two easy to use `MATLAB` codes for
computing resoances in one dimension. A more complete
package which allows refinement of parameters (necessary
for some computations) is available at

The complete and easily downloadable codes are

An example of the use of the first code is given in
Fig.1. The data is a vector of values,

computes the first (or so, depending on 's and 's) resonances for with

An example of using the second code is given in Fig.8. The data now are two vectors of the same length and
