Sets approximation or detail undecimated wavelet transform (UWT) coefficients at a specific level. Use the WA Undecimated Wavelet Transform VI to compute the UWT. Use the WA Get Coefficients of Undecimated Wavelet Transform VI to obtain the UWT coefficients.Use the pull-down menu to select an instance of this VI.
![]() | coef type specifies whether this VI sets the approximation coefficients or detail coefficients. The default is Approximation coefficients. |
![]() | UWT coef specifies the approximation coefficients and the detail coefficients from the multi-level undecimated wavelet transform (UWT). You must organize the coefficients in an array of waveforms starting with the approximation coefficients at the largest level followed by the detail coefficients at all levels in descending order. If you use the WA Get Coefficients of Undecimated Wavelet Transform VI to obtain the UWT coefficients, wire the UWT coef out output of the WA Get Coefficients of Undecimated Wavelet Transform VI to the UWT coef input of this VI. |
![]() | coef level specifies the coefficient level this VI sets. The coef level must be between 1 and the largest level of the coefficients. The levels in the WA Undecimated Wavelet Transform VI specifies the largest level of the coefficients. The default is 1, which means this VI sets the coefficients at level 1. If coef type is Approximation coefficients, this VI ignores coef level. If coef type is Detail coefficients, this VI sets the coefficients at the level you specify in coef level. |
![]() | error in describes error conditions that occur before this node runs. This input provides standard error in functionality. |
![]() | new UWT coef specifies the undecimated wavelet transform (UWT) coefficients to set. |
![]() | UWT coef out returns the undecimated wavelet transform (UWT) coefficients set to new UWT coef at the coef type and coef level. |
![]() | error out contains error information. This output provides standard error out functionality. |
![]() | coef type specifies whether this VI sets the approximation coefficients or detail coefficients. The default is Approximation coefficients. |
![]() | UWT coef specifies the approximation coefficients and the detail coefficients from the multi-level undecimated wavelet transform (UWT). You must organize the coefficients into a 2D real array starting with the approximation coefficients of the largest level at the first row followed by the detail coefficients of all levels in descending order. If you use the WA Get Coefficients of Undecimated Wavelet Transform VI to obtain the UWT coefficients, wire the UWT coef out output of the WA Get Coefficients of Undecimated Wavelet Transform VI to the UWT coef input of this VI. |
![]() | coef level specifies the coefficient level this VI sets. The coef level must be between 1 and the largest level of the coefficients. The levels in the WA Undecimated Wavelet Transform VI specifies the largest level of the coefficients. The default is 1, which means this VI sets the coefficients at level 1. If coef type is Approximation coefficients, this VI ignores coef level. If coef type is Detail coefficients, this VI sets the coefficients at the level you specify in coef level. |

![]() | UWT coef specifies the approximation coefficients and the detail coefficients from the multi-level undecimated wavelet transform (UWT). Each element of the array contains the 2D UWT results of one level. The ith element stores the approximation coefficients and the detail coefficients at level i+1. If you use the WA Get Coefficients of Undecimated Wavelet Transform VI to obtain the UWT coefficients, wire the UWT coef out output of the WA Get Coefficients of Undecimated Wavelet Transform VI to the UWT coef input of this VI.
