Transferring data to QMap

[saad_saadi]

Dear Sir,

Sorry for disturbing you again. Now i want to do the reverse, means what to transfer QFilterMap2D data to a 2D matrix. first let assume an example for QMapFilter1D, it will be like this

typedef QVector<double>  QFilterDataMap1D
typedef QMap<double, QFilterDataMap1D> QFilterDataMap2d
QFilterDataMap1d map1d;
QFilterDataMap2D map2d;
double gain;
double gain2[1][153];

typedef QVector<double>  QFilterDataMap1D
typedef QMap<double, QFilterDataMap1D> QFilterDataMap2d
QFilterDataMap1d map1d;
QFilterDataMap2D map2d;
double gain;
double gain2[1][153];

To copy to clipboard, switch view to plain text mode 

I want to transfer map2d into gain2. Can you please tell me how i can do this.

Thanks in advance.
