v128 v129 943 943 * ro2_patch: smoothing coefficient rho used for patch2 944 944 945 -'''List of field variables (old CIVx conventions):''' Aset of velocity vectors is defined by a 1D array of position coordinates x, y, and z for 3D civ, and a corresponding array for each of the velocity components u, v, and w for 3C civ. The field is therefore defined on an arbitrary set of point, without restriction to a regular mesh. Additional arrays are used to keep track of the quality of the PIV process leading to each vector. The image correlation maximum is represented by vec_C (a real number between 0 and 1). A flag vec_F represents a warning on the vector quality (see the list of values below). Another flag FixFlag marks false vectors: !FixFlag=0 for good vectors, and FixFlag is set to a non-zero value when it has been detected as false (using a 'fix' operation).945 -'''List of field variables (old CIVx conventions):''' a set of velocity vectors is defined by a 1D array of position coordinates x, y, and z for 3D civ, and a corresponding array for each of the velocity components u, v, and w for 3C civ.

Each column corresponds to an operation. 'filter1' and 'interp1' both result from the patch1 interpolation on the same points, with and without smoothing respectively. The first line is the name of the constant representing the number of vectors (the dimension of the arrays). The next successive lines indicate the variable names for the position and velocity components, the image correlation 'c', the 'flag' about civ quality and 'fix' flag (only available for civ1 and civ2), and the spatial derivatives obtained from the patch operations. … … 1009 1009 * 'view_field';...% function for visualisation of projected fields' 1010 1010 1011 === Functions activated by mouse and keybord in GUI :===1011 === Functions activated by mouse and keybord in GUI === 1012 1012 * 'keyboard_callback';... % function activated when a key is pressed on the keyboard 1013 1013 * 'mouse_down';% function activated when the mouse button is pressed on a figure (callback for '!WindowButtonDownFcn') … … 1022 1022 * 'RUN_STLIN';...% combine 2 displacement fields for stereo PIV * 'sub_field';...% combine the two input fields, 1023 1023 1024 === convert and I/O functions :===1024 === convert and I/O functions === 1025 1025 * 'cell2tab';... % transform a Matlab cell in a character array suitable for display in a table 1026 1026 * 'fill_GUI';... % fill a GUI with handles 'handles' from input data Param … … 1038 1038 * 'xml2struct'...% read an XML file as a Matlab structure, converts numeric character strings into numbers 1039 1039 1040 === ancillary functions :===1040 === ancillary functions === 1041 1041 * 'activate';...% emulate the mouse selection of a GUI element, for demo 1042 1042 * 'calc_field_interp': defines fields (velocity, vort, div...) from civ data and calculate them for projection with linear interpolation
