pi_nondim: Compute a unique non-dimensionalizing factor

In zdelrosario/piMat: Utilities for Dimensional Analysis

Usage

pi_nondim(u_dim, df_dim)

Arguments

u_dim

target dimensions; named vector, names must be in df_dim \item df_dimdimension matrix, must contain 'dim' character column

weights for non-dimensionalizing factor; named vector Compute a unique non-dimensionalizing factor ## Construct example df_dim <- tribble( ~rho, ~U, ~d, ~mu, ~dim, 1, 0, 0, 1, "M", -3, 1, 1, -1, "L", 0, -1, 0, -1, "T" )

u_dim <- c( "M" = 1, "L" = 1, "T" = -2 )

w_dim <- pi_nondim(u_dim, df_dim)

## Check proper dimensions named_inner(w_dim, df_dim)

## Check orthogonality df_proj <- pi_projection(df_dim) named_inner(w_dim, df_proj)
