4 Using MWArra y Classes

Row and column index arrays are used to construct the sparse array such that

the following holds true, with space allocated for

nzmax nonzeros:

S(rowIndex(k), columnIndex(k)) = realData(k) + imagData(k)*i

If you assign multiple values to a single rowIndex and colIndex pair, then

the element at that index is assigned the sum of these values.

rows and cols

Number o f rows and columns in the m atrix

nzmax

Maximum number of nonzero elements

MWClassID

representingtheMATLABtypeofthearray. TheonlyclassID

currently supported is MWClassID.DOUBLE.

Valid types for the

realData and imagData parameters are a s follows:

•

double[]

• float[]

• long[]

• int[]

• short[]

• byte[]

• boolean[]

• One-dimensional arrays of any subclass of java.lang.Number

• One-dimensional arrays of java.lang.Boolean

• One-dimensional arrays of java.lang.String
