load

Builtin index · File I/O

load(path)

Input: path · Output: no output

What it is

Restores every variable a save/save_all call wrote. path (string) is the file to read.

Overloads

One call shape — this function is not overloaded.

Examples

From the documentation, and run by the build -- the output and the figure below are what the engine actually produced. Simplest first.

write_csv(df, "data.csv")
df2 = read_csv("data.csv")
print(df2)
table.write(df, "data2.csv")
df3 = table.load("data2.csv")
print(df3)

x   y
-  --
1  10
2  20
3  -5
x   y
-  --
1  10
2  20
3  -5

from tour

x = 1 to 5
A = [1, 2; 3, 4]
m = ols_model([1;2;3;4], [2;4;6;8])   # a fitted model round-trips too

save_all("session.json")              # every variable currently in scope


# ...later, in a fresh session...

load("session.json")                  # restores x, A, m into the workspace

p = predict(m, [5])                   # -> [10]

from fundamentals

How it works

load(path) — restore every variable a save/save_all call wrote, under the same names, into the top-level workspace (overwriting any existing variable of the same name, the same "load replaces" semantics MATLAB's own load has).

From the note above this builtin in the interpreter, where the reasoning was written down as it was built.
