## New products

As the popularity of renewable energy sources increases, semiconductors can enable the efficient and safe transportation of energy to more homes, buildings and cities.

## Our passion

At our core, we have a passion to create a better world by making electronics more affordable through semiconductors. This passion is alive today as we continue to pioneer advances in integrated circuits. Each generation of innovation builds upon the last to make technology smaller, more efficient, more reliable and more affordable – opening new markets and making it possible for semiconductors to go into electronics everywhere. We think of this as Engineering Progress.

## 关于唐医生的一切

A female surgeon who has practiced medicine abroad for many years returns to China. She is appointed as the director of the Heart Center of Ankang Hospital where she establishes a critical illness team and heads the project to develop artificial hearts domestically. Most people could not accept that Tang Jiayu (Qin Lan) has come out of nowhere to become their boss. Nonetheless, she kept on proving 关于IQ Option期权平台上出金提款问题解答 herself through a series of difficult operations to conquer her subordinates one by one.

## xcorr

r 关于IQ Option期权平台上出金提款问题解答 = xcorr( x , y ) returns the cross-correlation of two discrete-time sequences. Cross-correlation measures the similarity between a vector x and shifted (lagged) copies of a vector y as a function of the lag. If x and y have different lengths, the function appends 关于IQ Option期权平台上出金提款问题解答 zeros to the end of the shorter vector so it has the same length as the other.

r = xcorr( x ) returns the autocorrelation sequence of x . If x is a matrix, then r is a matrix whose columns contain the autocorrelation and cross-correlation sequences for all combinations of the columns of x .

r = xcorr( ___ , maxlag ) limits the lag range from -maxlag to maxlag for either of the previous syntaxes.

r = xcorr( ___ , scaleopt ) also specifies a normalization option for the cross-correlation or autocorrelation. Any option other than 'none' (the default) requires x and y to have the same length.

[ r , lags ] = xcorr( ___ ) also returns the lags at which the correlations are computed.关于IQ Option期权平台上出金提款问题解答

## Examples

### Cross-Correlation of Two Vectors

Create a vector x and a vector y that is equal to x shifted by 5 elements to the right. Compute and 关于IQ Option期权平台上出金提款问题解答 plot the estimated cross-correlation of x and y . The 关于IQ Option期权平台上出金提款问题解答 largest spike occurs at the lag value when the elements of x and y match exactly (-5). ### Autocorrelation of Vector

Compute and plot the estimated autocorrelation of a vector x . The largest spike occurs at zero lag, when x matches itself exactly. ### Normalized Cross-Correlation

Compute and plot the normalized cross-correlation of vectors x and y with unity peak, and specify a maximum lag of 10 . ## Input Arguments

### x — Input array vector | matrix | multidimensional array

Input array, specified as a vector, matrix, or multidimensional array. If x is a multidimensional array, then xcorr operates column-wise across all dimensions and returns each autocorrelation and cross-correlation 关于IQ Option期权平台上出金提款问题解答 as the columns of a matrix.

Data Types: single | double
Complex Number Support: Yes

### y — Input array vector

Input array, specified as a vector.

Data Types: single | double
Complex Number Support: Yes

### maxlag — Maximum lag integer scalar

Maximum lag, specified as an integer scalar. If you specify maxlag , the returned cross-correlation sequence ranges from -maxlag to maxlag . If you do not specify maxlag , the lag 关于IQ Option期权平台上出金提款问题解答 range equals 2N – 1, where N is the 关于IQ Option期权平台上出金提款问题解答 greater of the lengths of x and y .

Data Types: single | double

### scaleopt — Normalization option 'none' (default) | 'biased' | 'unbiased' | 'normalized' | 'coeff'

Normalization option, specified as one of the following.

'none' — Raw, unscaled cross-correlation. 'none' 关于IQ Option期权平台上出金提款问题解答 is the only valid option when x and y have different lengths.

'biased' — Biased estimate of 关于IQ Option期权平台上出金提款问题解答 the cross-correlation:

R ^ x y , biased ( m ) 关于IQ Option期权平台上出金提款问题解答 = 1 N R ^ x y ( m ) .

'unbiased' — Unbiased estimate of the cross-correlation:

R ^ x y , unbiased ( m ) = 1 N − | m | R ^ x y ( m ) .

'normalized' or 'coeff' — Normalizes the sequence so that the autocorrelations at zero lag equal 1:

R ^ x y , coeff ( m ) = 1 R ^ x x ( 0 ) R ^ y y ( 0 ) R ^ x y ( m ) .

## Output Arguments

### r — Cross-correlation or autocorrelation vector | matrix

Cross-correlation or autocorrelation, returned as 关于IQ Option期权平台上出金提款问题解答 关于IQ Option期权平台上出金提款问题解答 a vector or matrix.

If x is an M × N matrix, then xcorr(x) returns a (2M – 1) × N 2 matrix with the autocorrelations and cross-correlations of the columns of x . If 关于IQ Option期权平台上出金提款问题解答 you specify maxlag , then r has size (2 关于IQ Option期权平台上出金提款问题解答 × maxlag + 1) × N 2 .

For example, if S has three columns, S = ( x 1 x 2 x 3 ) , then the result of R = xcorr(S) is organized as

R = ( R x 1 x 1 R x 1 x 2 R x 1 x 3 R x 2 x 1 R x 2 x 2 R x 关于IQ Option期权平台上出金提款问题解答 2 x 3 R x 3 x 1 R x 3 x 2 R x 3 x 3 ) .
