我有一個問題。如何連接列表中的矩陣
我有代碼:
RootBootstrapping <- function(mean, sd)
{
polyCoeffs <- rnorm(length(mean), mean = mean, sd = sd);
rawResult <- as.complex(polyroot(polyCoeffs));
roots <- rawResult[order(Re(rawResult), Im(rawResult))];
rootMatrix <- matrix(nrow = (length(polyCoeffs) - 1), ncol = 2);
colnames(rootMatrix) <- c("Re", "Im");
rootMatrix[,"Re"] <- Re(roots);
rootMatrix[,"Im"] <- Im(roots);
return (rootMatrix);
}
points <- 5
polyMatrixCoeff <- matrix(c(1, 0, 0.5, 0.01, 0.3, 0.02), nrow = 3, ncol = 2);
colnames(polyMatrixCoeff) <- c("mean", "sd");
meanRoots <- as.complex(polyroot(polyMatrixCoeff[,"mean"]));
rootsCount <- length(polyMatrixCoeff[,"mean"]) - 1;
我想從RootBootstrapping的多次運行串聯「byrow」的結果 - 我想有NX2矩陣「重」和「IM」欄目。
但下面的代碼無法正常工作......
rootsMatrix <- rbind(sapply(1:points, function(i)
{
roots <- RootBootstrapping(mean = polyMatrixCoeff[,"mean"], sd = polyMatrixCoeff[,"sd"]);
print(roots);
return (roots);
})
);
rootsMatrix
運行這段代碼,我有:
Re Im
[1,] -0.8396051 -1.614007
[2,] -0.8396051 1.614007
Re Im
[1,] -0.8826579 -1.650071
[2,] -0.8826579 1.650071
Re Im
[1,] -0.8182654 -1.600865
[2,] -0.8182654 1.600865
Re Im
[1,] -0.7379369 1.566913
[2,] -0.7379369 -1.566913
Re Im
[1,] -0.7958687 -1.575169
[2,] -0.7958687 1.575169

[4,] 1.6140074 1.6500706 1.6008651 -1.5669132 1.5751692

,但我想這一點:
Re Im
[1,] -0.8396051 -1.614007
[2,] -0.8396051 1.614007
[3,] -0.8826579 -1.650071
[4,] -0.8826579 1.650071
[5,] -0.8182654 -1.600865
[6,] -0.8182654 1.600865
[7,] -0.7379369 1.566913
[8,] -0.7379369 -1.566913
[9,] -0.7958687 -1.575169
[10,] -0.7958687 1.575169
那麼,是什麼我應該爲「byrow」矩陣連接做些什麼?
謝謝。
是的!謝謝! – Dmitriy
是的,我已經這樣做了。 ))Stackoverflow允許在同一時間後(10分鐘,我想:-() – Dmitriy
