Hi
This Java project has developed by Pooya husseini to design a command line interface to create, save, load and manipulate Matrices and values. It has purely written in Java. I've used maven, spring and freemarker to decrease the production time. First of all Run Program.java class,for example write Matrix a 3 3, and see that it will create a 3x3 matrix named 'a'. You can separate commands in a line with ';'. Commands are not case-sensitive.

There is the full command list: #object is both values and matrices

add [ #matrix_store_name ] #object_name1 #object_name2

Adds one object to another

copy [#matrix_store_name] #object_name1 #object_name2

Copies one object to another

del #object_name [ #object_name... ]

Deletes the given object

det [ #val_store_name ] #matrix_name

Calculates determinant of the matrix and puts in the given value

echelon [ #matrix_name ] #matrix_name

Calculates the echelon form of the object

inv [ #matrix_store_name ] #matrix_name

Inverts the object

lu #matrix_a #matrix_l #matrix_u

Solves the lu decomposition

matrix #matrix_name [#height #width]

Creates a matrix with dimension of height * width.

mul [ #matrix_store_name ] #object_name1 #object_name2

Multiplies one object to another

pow [ #matrix_store_name ] #object_name [#integer|#val_name]

Powers one object to the entered number or value

rank [ #val_store_name ] #matrix_name

Calculates the rank of the object

read #object_name #file_path

Reads object from file-path and stores it with the given name

save #object_name #file_path

Stores object in the given file path

set #object_name [[#row]][[#col]] [{ #values... }]

Fills object with values according to values

show #object_name [ #object_name... ]

Prints then string representation of the object in console

solve #matrix_x #matrix_a #matrix_b

Solves the equation of Ax=b

sub [ #matrix_store_name ] #object_name1 #object_name2

Subtracts one object to another

swap #object_name1 #object_name2

Swaps two objects

trace [ #val_store_name ] #matrix_name

Calculates the trace of the object and puts in the given value

trn [ #matrix_store_name ] #matrix_name

Transpose the object and puts it in the given val

var #val_name [ #number ]

Defines a single value with the given value

usage #command_name [ #command_name... ]

Prints how to use the command_name

help #command_name [ #command_name... ]

Prints about the command_name
