Examples

# \donttest{
# Create small example
mat <- matrix(rnorm(20), nrow = 4, ncol = 5)

backend <- matrix_backend(mat, mask = rep(TRUE, ncol(mat)))
dataset <- fmri_dataset(backend, TR = 1, run_length = nrow(mat))
fs <- fmri_series(dataset)

# Convert to matrix
mat_result <- as.matrix(fs)
dim(mat_result) # 4 x 5
#> [1] 4 5
# }
