The difference in depth between the high and low frequency channel (High - Low).The difference in depth between the high and low frequency channel (Low - High).Elevation recorded with the high frequency channel of your echo sounder.Elevation recorded with the low frequency channel of your echo sounder.Depth recorded with the high frequency channel of your echo sounder.Depth recorded with the low frequency channel of your echo sounder.You can use this setting to select which data of the sounding is used to generate the matrix. Select which boundaries to include in the When no boundary has been selected, the data points of the selected soundings will be used to determine the area that needs to be filed with data. This can be used in cases when only a part of the sounding areas has to be interpolated. When an island or clipping boundary is selected, it will be used to determine which area's should be filled with data and which are not. When a boundary is defined as a shoreline, including the boundary will automatically include the data points defined on this line. In Hydromagic, boundaries can be used do define a shoreline, a clipping area or an island. Select which sounding(s) to include in the By clicking the "Select." button, you will be able to select one or more soundings that will be used to calculate the triangulation from which the matrix or digital terrain model will be generated. Select from which sounding(s) you wish to generate the matrix. Use the "Generate Matrix" utility to generate a matrix by using a TIN algorithm. To do so, open the "Generate Matrix" dialog by selecting rthe "Generate Matrix." option from the "Tools" menu: In order to generate the matrix, you have to specify some settings, like the data being used to generate the matrix, as well as some output options. Use the " Generate sounding wizard" to generate sounding(s) from your raw data file(s) first. Without the sounding or shoreline data it is not possible to generate a matrix. To generate a matrix, you must have a either a valid sounding or a shoreline containing depth information loaded into your project. The image below shows a color matrix which has been generated using TIN (data points at 0.25 meter interval).Įxample matrix generated from sounding and boundary data. All new data points are generated by "filling" the triangles, which have been formed from the scattered data. This TIN is generated using a Delaunay triangulation algorithm. A matrix can be used to view a 3D model of the terrain using the " 3D Terrain Viewer", in volume calculations or to generate depth contours.ĭuring the generation of a matrix from a sounding, the scattered data points are converted to regularly spaced data using a TIN (Triangulated Irregularly Network). Such data is also referred to as a digital terrain model or DTM. Return '\n'.join(' '.join(str(c) for c in self.tab) for i in range(self.In Hydromagic, a matrix is a collection of regularly spaced depths, which can be projected over the map as color or text. Finally, I added some code to demo that this code does work: class zcomplex:ĭef _init_(self, real=0 ,imag=0, rows=3): I also added _repr_ methods to make it possible to trivially print the contents of instances of each of your classes. Here's a version of your code with changes for the two things I mention above. So you need to build each row a bit differently. Likewise, *self.rows will create a list with 3 references to the same zcomplex object. *self.rows will create a list with 3 references to the same tuple, which isn't what you want, right?. What you're doing to build each row of your matrix won't work. A zmatrix is a container of zcomplex objects. A matrix, after all, isn't itself ever a complex number. I don't understand what you expect to gain by having zmatrix inherit from zcomplex. Here's your code with the simple change that will do that: class zcomplex: If you want tab.real to be a valid expression, then you have to create tab as a matrix of zcomplex objects. } /*zmatrix zmatrix :: operator*(const zmatrix& TABLICA) Zmatrix temp(rows,columns) for(int i =0 i < rows ++i) In c++ i can: zmatrix zmatrix :: operator-(const zmatrix & zarray) How i can fix this problem without numpy?įor tab.real I meant how overload operator +,- and * Self.tab=*self.rows for i in range(self.rows)] class zcomplex:ĭef _init_(self, real=0,imag=0,rows=3): Tmp.tab+= self.tab * other.tabīut i want by means of inheritance similar in C++. Self.tab=*self.rows for i in range(rows)] My first method work with one class and complex(self.real,self.imag) : I am trying to create complex number matrix class using Python.
