resize_matrix

Arguments

mat

input matrix from which the resized matrix will be created.

nbRow

number of row of the resized matrix.

nbCol

number of column of the resized matrix.

typeOfMat

caracter string, type name of the resized matrix.

resMat

resized matrix.

Description

Create a matrix of size nbRow x nbCol and whose elements (i,j) are mat(i,j) if (i,j) is in the range of the input matrix. Otherwise elements (i,j) are 0 for real or integer matrices, %f for boolean matrices and an empty string for string matrices.

The type of the output matrix may be modified by specifying the typeOfMat argument. In this case, be sure that the input matrix type is compatible with this one.

For now, only real, integer matrices, boolean and character string matrices are supported. This means that typeOfMat must be chosen within: 'constant', 'boolean', 'string' or any integer type ('int8', 'int16',...).

Examples

// number matrix
myMat = 5 * rand( 3, 4 )
myMat = resize_matrix( myMat, 3, 3 ) // reduce the matrix size
myMatInteger = resize_matrix( myMat, 4, 4, 'int32' ) // create an integer matrix
myMatBoolean = resize_matrix( myMat, 2, 2, 'boolean' )
myMatBoolean = resize_matrix( myMatBoolean, 3, 5 )

// string matrix
myMatString = ["Scilab","the";"Open Source","Scientific";"Software","Package"]
myMatString = resize_matrix( myMatString, 3, 1 )
