This example describes how to use the ADC and DMA to transfer continuously converted data from ADC to a data buffer. The ADC is configured to converts continuously ADC channel14. Each time an end of conversion occurs the DMA transfers, in circular mode, the converted data from ADC1 DR register to the ADC_ConvertedValue variable. The ADC1 clock is set to 14 MHz.

This example provides a description of how to use a DMA channel to transfer a word data buffer from memory (Flash) to memory (RAM). The dedicated DMA channel is configured to transfer once a time a 32 word data buffer stored as constant in the Flash memory to another buffer in the RAM memory. The received data are stored in the DST_Buffer. The DMA channel transfer complete interrupt is enabled to generate an interrupt at the end of the buffer transfer. As soon as the transfer is completed an interrupt is generated and in the DMA channel interrupt routine the transfer complete interrupt pending bit is cleared. The data counter is stored before and after the transfer to show that all data has been transfered. TransferStatus gives the data transfer status where it is PASSED if transmitted and received data are the same otherwise it is FAILED

Probabilistic Principal Components Analysis. [VAR, U, LAMBDA] = PPCA(X, PPCA_DIM) computes the principal % component subspace U of dimension PPCA_DIM using a centred covariance matrix X. The variable VAR contains the off-subspace variance (which is assumed to be spherical), while the vector LAMBDA contains the variances of each of the principal components. This is computed using the eigenvalue and eigenvector decomposition of X.
