# Google Earth Engine Matrix Multiply Error?

In the below code, Tasseled Cap algorithm computed using array based computation but returns error and I don't know how can I solve this:

``````Map.centerObject(table);

var lc8 = ee.ImageCollection("LANDSAT/LC08/C01/T1_SR")
.filterDate('2018-01-01','2020-01-01')
.filterBounds(table)
.filter(ee.Filter.calendarRange(7,9,'month'))
.filter(ee.Filter.lt('CLOUD_COVER',10))
.map(function(img){
var bands = img.select('B[2-7]').multiply(0.0001).clip(table);
return bands.copyProperties(img,['system:time_start','system:time_end',
'system:index'])
}).median();

print(lc8);

var coefficients = [
[0.3029, 0.2786, 0.4733, 0.5599, 0.508, 0.1872],
[-0.2941, -0.243, -0.5424, 0.7276, 0.0713, -0.1608],

[-0.3294, 0.0557, 0.1056, 0.1855, -0.4349, 0.8085],
[0.1079, -0.9023, 0.4119, 0.0575, -0.0259, 0.0252]];

var bands = ['B2','B3','B4','B5','B6','B7'];

var arrayImage1D = lc8.select(bands).toArray();

print(arrayImage1D)

var arrayImage2D = arrayImage1D.toArray(1);

var componentImages = ee.Image(coefficients)
.matrixMultiply(arrayImage2D)
.arrayProject([0])
.arrayFlatten(
[['brightness','greenness','wetness','forth','fifth','sixth']]);

print(componentImages);
